I think you're conflating "large coordinated action" with "the Internet." They look similar, but it's more that a critical mass of not-Russia is deciding to stand up to Russia because Russia's political action in this situation is some seriously beyond-the-pale early-20th-century war of conquest stuff.
There is some consolidation happening (mostly around the fact that a lot of the companies we regularly use are "Western" and most of the governments of the West have imposed sanctions on Russia that those companies have to comply with), but it's also a that the meme has taken hold that (a) Russia deserves to be opposed and (b) sanctions and cutting-off are an effective way to oppose them.
