The open minded tech comminity can move mountains but this is now bigger than a mountain.
At this point about the only slingshot manouevre that could help us escape this fate is a reasonably resourced sovereign entity fully underwriting an open source stack (desktop, mobile, browser, cloud, fediverse) and nudging / seeding a mass user base by making it mandatory for engaging with public functions, paying taxes, transacting is sovereign money etc.
Effectively by declaring a tech "liberation" war.
I don't give this scenario high odds of happening but hopefully not every sovereign is captured. History is not made by the dazed and confused indulging in debilitating apathy.
