Take Coinbase for example. Google shows the current market cap is $50.95 billion and (in 2023) it had 3,416 employees. They're on the stock market, that comes with corporate decision making. Its not a company where someone in the PR-department can easily get a couple thousand dollars per week in Bitcoin to pay for a signature campaign on Bitcointalk. Large corporations can't just make payments to anonymous users on Bitcointalk. Some users here are from sanctioned countries, and sanction violation is not something they're going to risk.
