I don’t have any sources for you. But I saw it with my own eyes and took screenshots.
Sorry to link to reddit, but here’s a post with 90k up votes, and comments filled with people experiencing the same.
While being able to search #republican and #prolife
This is such a dumb thing to say, you could also say that all news papers etc. Are private companies.
But if they’re collectively controlled by a few people or the government, and only publish certain things. That is 100% censorship
They’ve since fixed it, and called it a bug.
A bug that only effects democratic content…
It’s no longer censored as obviously.
Once it made news they back pedaled
Nope you could search that just fine. 
Fair, it’s easier to ditch some than others.
Explaining to my work why I don’t use WhatsApp is tricky.
Sadly it’s true.
I’d love to move away from it, but my work and literally everyone I know is on there
It sounds like it only affected Instagram

They reversed it when it started making the front page of reddit etc.
It works again for me now, they’ll just shadow ban it now.

Must be China Trump and his Oligarchs can’t do anything wrong they’re protecting our freedom /s
They will now shadow ban these topics, so people can catch them red handed. But users will just never see it in their feed
There are articles about it

Instagram back pedaled, I can also search it now.
There are many news articles about it, most if not everyone was experiencing it.
fuckputin is still blocked for me
This is my instagram, I deleted facebook
Occam’s razor disproves this to me.
It’s more likely that meta was testing censorship, but people caught on.
Than #johnOliver #bernieSanders #Democrat #proChoice etc. All being banned, but none of the conserve hashtags
