Community backlash will be fierce if it's not actually runnable.

Ubisoft doesn't have the most stellar reputation for example (I don't work there anymore) so people look at things we do by accident as if they are intentionally malicious.

Also, the California law is one law, the EU is also looking at this and it's likely to look different - that's why "Stop Killing Games" doesn't really mean anything yet, even people within the movement have differing definitions.

The key is communication. If the company says the binary has a certain min. requirement, then the vast majority of people will accept that.

Of course there'll be idiots, but I doubt you'll see a stronger backlash than to a company shutting down the servers without any solution, like they can do now.
