Its not that they adopted, it's that 85-90% of bitcoin users are kyc'd and identified and now under surveillance by governments, tax authorities, chainalysis and blockchain analytics firms, and bitcoin can be censored, have their bitcoin seized, or accounts frozen. They now totally control it. People say stuff like "they can't stop me from using my bitcoin", ok, true, but they can arrest your for noncompliance with whatever rules they role oput, and extract wealth from you for using bitcoin. This defeats the entire purpose.
