You can use whataboutism to justify anything, but even your example is bad. Twitter admitted they got that wrong and Dorsey apologized: https://www.cnbc.com/2020/10/16/twitter-ceo-jack-dorsey-says...

I don’t see any apologies for any of the bad actions Twitter has taken since the purchase, and the hypocrisy of doing this while claiming to be a center of free speech is astounding.

Of course Twitter had bias before because every group of people has a bias. But that doesn’t mean that everything they do is wrong or malicious, just because you don’t like them. The real tragedy is letting your own bias blind you to what’s in front of your face.
