Facebook's been extensively cooperative with Russia, so I hardly see a 'even Whatsapp (which belongs to Facebook)' argument there. It's probably more of a 'Russia cannot continue to pay us, so best wishes guys, you can have advocacy again when you're able to pay for it'. It's just business.

The smaller services that go UP against the tech giants and have Russian backing, those will be cooperating with Russia. I don't know if Telegram counts as that or not, as I haven't looked into it. But they exist, and a lot of 'em are left scrambling now as the money dries up.
