Except electric cars are hell expensive and linux is free.

That was literally my point. Some people bought electric cars because the could, not because they wanted to effect any social change.

But other FOSS software (like the ActivityPub protocol) can for sure make a very sizeable dent in the amount of doomscrolling in one’s life.

Is activity pub only used on Linux desktop apps? Can't a Mac or windows user participate in mastodon? Fediverse use and Linux are separate issues.

This false equivalence between Linux itself and the path of our collective salvation from social media, corporate manipulation, etc, etc is a big problem for Linux, because Linux is just a tool.

btrfs is widely praised... and also a product of Facebook. Google has poured Fons of money into FOSS development. Should we shun these tools?

Especially now, with a sizable influx of users to Linux, articles like the one Op posted create a completely false us v them narrative that just isn't there.

You want to fight the evil social media? Drop them.
