I disagree, there's tons of new companies adopting Solana. In terms of infrastructure, pretty recently Google Cloud added Solana Hosted nodes for next year
https://cloud.google.com/ and crypto payments platform Poof adding Solana payments
https://www.poof.io/.
There's tons of other development going on with new projects launching daily. It's still early on, especially with all the DDOS attacks on the nodes. However, the future is bright.
This doesn't really help if the community moves out. And it doesn't really matter if some platform accepts payments with certain cryptos. Remember verge and pornhub?
There are numerous reasons why someone accepts specific crypto as payment. They could be paid to endorse it, or that they saw that there was potential buyers with it. I mean as long there's enough liquidity and they can easily at the moment of buying convert it to cash, why shouldn't they accept it.
What it comes to Google, they often want to help out and ofter packages for startups, and it's not just only google, microsoft is known to offer their services to startups as well.
I really am hoping that everything works out for Sol and it has a great community, but community can turn toxic and bitter too. There's no loyality in groups when people lose enough money.
