This seems unhealthy and obsessive at this stage... I've been on Reddit for more than 15 years (don't even remember exactly, my account was 15 years old but I lurked without logging in for a long while before that) so I understand letting go can be hard, but I think it's just better for your mental health to do so. Don't ragebait yourself, don't expect that any protest will work - it will not, and reddit will only show potential investors massive engagement numbers when they propose to infest r/place with ads.
Just give up - that fight is lost, and we can now have our fun here. We couldn't save Digg before, and we can't save reddit now. I have moved on and it was actually easier than expected. I wholeheartedly recommend it to anyone - just don't engage with reddit and talk to us here!
