Even if the only thing it brings is the recognition of Bitcoin becoming more popular, it's definitely not nothing. We all have been discussing cryptocurrencies for years, we remember a lot of ups and downs and various claims of people and companies. It seems like we are a big community, but there aren't even 100 million crypto users in the world. And many people who heard of it either know that it's the money of drug dealers or that it's a bubble/ponzi. The fact that reputable companies add the symbol of this currency proves that they don't think it's one of these. In this particular case the symbol is available along with thos of fiat currencies, which also means an important and not very common recognition of bitcoin as a currency rather that pseudo-security or commodity.
