I don't think people realize how horrifying these addendums are.
Not only do they not really fix the issue, but they prove that no, yeah, they hadn't thought about the possibility of "install bombing" at all until just now and it would totally have triggered massive fees.
I mean, the announcement was terribly worded, and some of the stuff (like wha't a "monthly fee" or a "retroactive fee") were very unclear, so you could hold out hope that they knew what they wanted to do and were just bad at explaining it.
But nope, that ship has sailed. They clearly didn't give this any amount of thought.
So yeah, I'm more worried about it now than I was yesterday, believe it or not. Like, a LOT more.
Yeah this feels like Wizard of the Coast's first response to the OGL drama. Make some changes that are technically better than the first terrible system, but is ultimately still completely unacceptable. WotC eventually had to walk back everything, we'll see if Unity does the same.
But honestly at this point that's not even enough. You know they tried, you know whatever need for cash they were trying to fulfill remains. It's one thing to let that go when buying a piece of software that you just... have, but building an entire business on top of this middleware and knowing you have a business relationship with them indefinitely as a result?
At this point it's a dealbreaker. You can't trust them again. If I start a new dev studio tomorrow Unity would not even be in the running to start choosing an engine. They made themselves into a liability overnight. It's stunning. I don't know what the hell they're putting in the filtered, flavored water they sell to executives, but this year has been an endless chain of self-immolation I had never witnessed before.
Not to mention the OGL stuff was only a risk to 3PP as a lawsuit of WoTC decided to act on it. This debacle is a direct attack on the bottom lines of games publishers that will kill independent development and seriously hamper even AAA companies. I know I'm not going to waste my time learning it.
This is exactly what I said to my friend today as we were discussing it. The only times I've seen companies make a crazy move like this that will make them more money in the short term but screw themselves in the long term is when they're trying to sell the company. The new company won't care much about the bad publicity because they'll just come in after the sale and tome down some of the changes and suddenly everyone thinks they're the good guys.
