It is true that there are a lot of scams, and many crypto projects are scam projects, but that doesn't apply to Bitcoin. Bitcoin can be involved in scam, just like any other form of money in the world. But Bitcoin itself is certainly not a scam.
Altcoin projects can be scam at project level, as they plan it since the start but Bitcoin is not a scam project at project level. Satoshi Nakamoto did not ask any money, didn't do any ICO, IEO or the likes to get money from community.
So if Bill Gates says he likes Bitcoin suddenly you'll use Windows 11?, again, makes no sense.
You nailed it!
If Elon Musk says he will ban iOS on all products of his companies like Tesla if Apple partner with OpenAI at OS level, will people stop using products of Apple?
It makes no sense. Using or not using, it can be from many reasons, budget, security concern and more. Therefore, many people are not fan of any company or OS, they can use products, OS from different companies.
