XRP wasn't a stablecoin anyway. Also, we should consider a fact that Ripple as company has more important stuff to worry about such as partnerships with banks.
Situation is much different with Tether though
Tether is also a company, that is the root of all the problems as well and thats why people should have stayed away from it. Ripple is a company, their product is XRP, they sold people countless amounts of XRP and used that money to make themselves richer and also used the system to work with financial institutions and they spent time on these type of scammy shady stuff.
Tether is not that different from that logic, sure it is stablecoin which makes it a bit different, but they printed out 20+ billion dollars worth of USDT and the only thing they said is "we got you covered" in case anyone wants to get out, but since the market covers it themselves whenever someone wants to sell, and whenever there is too much sell and price "looks" like it is dropping, arbitrage people handled it, so Tether rarely ever gets cashed out and usdt rarely turns into usd. Which is why as a company they should have been looked at a lot earlier.
