What I have seen, essentially wall-to-wall across social media, for the past week:
-'Why is no one talking about [this atrocity]?'
-'Why are people talking about [this injustice and not that injustice]?' (Often two different posts by two different people, in quick succession, with said injustices reversed.)
-'What you are doing in response to [this injustice] is insufficient.'
-'If you haven't mentioned [this atrocity] on your social media, you're part of the problem.'
-'If you've mentioned [this injustice and not that injustice] on your social media, you're a hypocrite and part of the problem.'
-'You're protesting the wrong way.'
-'Protesting when it's permitted by the state isn't real protest.'
-'These protests are all a bit cringe, aren't they?'
-'You're condemning [this atrocity], but not in the right way.'
-'You're condemning [this atrocity], but far too late.' (This coming, without irony, from the same people I witnessed several years ago saying, 'it's never too late to find courage and speak out publicly against [this same atrocity].')

What I have seen, in much smaller numbers — a little fragment struggling to stay afloat in the deluge:
-'[This injustice] is an injustice for these specific reasons, and here is something concrete that anyone reading/viewing this post can do to help.'

Needless to say, whenever I witnessed the latter, I actually did the things suggested, and felt much more of a sense of agency and purpose, than when I saw the former.

(And obviously I recognise the irony of being irritated by people complaining about what they see/don't see on social media rather than trying to offer concrete solutions to the consequences of major (geo)political injustices ... and then writing a whole post complaining about what I see/don't see on social media. But I am just. so. tired.)
