Of course they will! This is the sad, sad reality of todays internet - the power is so centralized in the hands of like 4 companies, that every business basically can't ignore them. Like you can but by that you're just hurting yourself from the business point of view. Elon Musk can literally say Fuck You to advertisers and they still need to advertise there. This is just crazy. On nation level the anti-monopoly bureau would take action but we don't have world wide anti-monopoly bureau.

That's why when people tell me "Oh, Elon Musk just bankrupted Twitter" I say "Did he?". At this point I believe he can do anything he wants, he can murder like dozen people, blow up the headquartes or start selling drugs to children and Twitter would still be fine
