Have you noticed that recently there has been a large number of new stablecoins appearing?

USD0 - a coin from the USUAL project, which was launched in December of last year

USDE - a project from ENA

Ripple USD (RLUSD) - a stablecoin launched by XRP. I wrote a detailed article about it RLUSD

USDY - a coin from ONDO that was launched in March of last year

My version of this phenomenon is as follows: large projects realized that they could launch their own stablecoin and profit from it.

Also, why integrate someone else's stablecoin into your blockchain if you can create your own coin - this is what XRP did.
