This is misleading. Not sure if by ignorance or malice, but it's very misleading.
This isn't happening with your browser bookmarks. This is Google Collections, which is a shareable bookmarking feature, meaning it can be made publicly available. That's why it's moderated. It's basically Google's version on something like Pinterest.
They have a duty to moderate public-facing systems. This is a link/bookmark sharing system, so obviously bookmarks that are pointing to things that are illegal are going to be dealt with.
I'm pretty sure there are reasonable expectations by governments that you maintain adequate moderation, especially the EU. If Mozilla were to deploy a public facing system and not moderate it, they would catch hell from the EU and likely be fined out the ass.
If you're going to store something on someone else's computer (Google cloud), they have every right to control what is and is not allowed on their systems. Don't like it? Use encryption, selfhost, etc...
So if you have a collection with political targets and the folder is just google maps links to their houses with their names as the bookmark name google shouldn't be allowed to stop you from spreading this?
Sure google is shitty but this feature is designed to share links with other people and sometimes those links can be dangerous so imho it's absolutely necessary to moderate them at some level.
Every single comment chain on this thread besides this chain are 100% wrong and operating on misleading information. I fucking hate how up in arms people get when they don't even have the full picture - even the basics, like having read the fucking article.
