OP is upset about something that he also partakes in, all be it from the sidelines, but that doesn't really matter because it's still taking part.
It's basically easy free/low cost entertainment.
If you're watching tv and something comes on that you don't like, most people just change the channel, but I guess you could also go online and complain about why you don't like the programme, similar to what OP is doing here.
As others have suggested, if you don't like it, simply delete social media.
