I got disinterested in XRP back in March 2020 when I learned about the 20 XRP wallet minimum. That was a deal breaker for me because it requires people to invest some money that they will never be able to access again. Also, I did not like how XRP is centralized. But now, with the giant lawsuit, why are people still buying?
I actually got turned off XRP for exactly the same reasons as you.
The team doesn't seem to care about lowering the 20 XRP minimum, which should be the most logical thing to do after their coin went on a price hike for the ages. And although their main selling point was that they are a coin with real, fiat-world sponsors, that is really a double edged sword - it also means that their coin is totally centralised and really no different to fiat-economy financial services.
But it actually makes sense that people are buying. You have to take into account the price at which they are buying at, which is a huge discount compared to the highs of 2017. The majority are simply speculators looking to time a rebound, and/or hoping for some regulatory changes.
You have to understand that even the worst altcoins can be a bargain at a certain price.
