GPLv3 is virally open source (copyleft), BSD 2-Clause is not.
Your first statement is patently false and misleading.
Two variants of the license, the New BSD License/Modified BSD License (3-clause), and the Simplified BSD License/FreeBSD License (2-clause) have been verified as GPL-compatible free software licenses by the Free Software Foundation, and have been vetted as open source licenses by the Open Source Initiative. (Wikipedia)
Being “copyleft” is not a requirement for being open source. Maybe you’re thinking of free software. There are differences, but as the FSF is quoted, they are also very similar.
GPLv3 ensures free software remains free and contributions cannot be exploited and withheld from the community. BSD2C does not.
To my understanding, and if I’m wrong I’d love to know why, both GPLv3 and BSD2 both ensure the openness of software. They just go about it differently. GPL (I’m not super versed at v3) basically means any modifications to GPL’d code must also be GPL’d, and source made available; also, if you statically link against other GPL’d code, your code must be GPL’d. Dynamic linking (or linking against LGPL code, like glibc) does not have this requirement.
With BSD code, your only requirement is that the code (or binaries) must remain BSD2. Sure, someone can make modifications and keep them to themselves for fun and profit. But that doesn’t mean the rest of the community has to follow suit. The original code remains open and available with no license modifications. If a company owns BSD2 code, and goes under, the community can simply fork the code and take ownership as they please.
Neither license is perfect, and I’m sure we could find plenty of examples of people/companies that have abused both licenses.
The person who responded made provably false statements. I know they are false, because I went to look it up; which is outlined in my “[whooped] out references”.
GPL is virally open source, because code using it needs to also be open source.
According to your comment, that doesn't apply to BSD, so BSD isn't virally open source, and the claim is true.
The reason some consider this better is because a company can't fork the code, keeping it private, improving their version with paid workforce while also merging in changes to the original project, thus ending up with a superior version that they can then sell for profit, to no benefit of the opensource version or the people contributing to it.
There's more reasons, and a whole ideological side, but I think that's the main practical reason for using copyleft licenses, and a big one.
Nothing I said is remotely untrue, for a start. Both licenses - and their pros and cons - are well documented, well-tread territory. It’s weird that you even had to ask.
And really weird how you seem to be taking my comment so personally while simultaneously spreading misinformation, literally admitting that you don’t know what you’re talking about (“not very well versed”) AND putting words in my mouth. 🤷🏽
GPLv3 makes a company publish the source under the same license. That means no Vivaldi, Chrome, Edge or any other spyware ad ridden browsers. I don't think we need more lock in.
I understand your reasoning, but I think your logic is flawed. If Ladybird is GPLv3, then browsers will continue to use Chromium base which helps the Chrome monopoly. By making it BSD, it will help others adopt it.
I'd favour GPL3 too, but we do need wide adoption because that's the only way an independent browser will influence websites not to just design for Chromium. That needs to happen for the new browser to have any impact on Google's ability to dictate standards unilaterally.
Given the complexity of creating a new browser securely (or at all) then this suggestion is not good.
We already have projects that focus on smaller parts of a web browser (e.g a video player) which are free software. We should work on those and encourage their use over all browsers.
That is a massive undertaking that hasn't been done in a very long time. Modern browsers have either been around for 20 years or are forks. (Sometimes both)
We are taking about creating something from scratch. That can take 5-10 years to do.
The good news is that we have plenty of tools on our tool belt. Think browsers such as Mull and Librewolf plus extensions like ublock.
I'm normally in the camp that copyleft prevents enterprise adoption, and therefore limits users/contributors... but in this case I agree. I'd like browsers to be copyleft. I'd like to be able to see what kind of sketchy shit Edge and Chrome are throwing on top of Chromium and have it out in the open.
Question for the free software community...
If I used a headless version of a copyleft browser as part of an automated testing suite for proprietary enterprise software, does that violate the copyleft license?
