This news looks more like Visa throwing tantrum in Tether company and other stable coins because they are gradually been used as an alternative to send and receive payment and perhaps Visa customers has shrink over the years.
I am willing to bet visa crypto cards see more real-life activity than any of those stable coins, in chasing and buying stuff.
Also, I don't understand why iemdiately on the defense and arguing they are lying, Bitcoiners have put Visa and Bnkas under a mcrisope for a decade, they have always blamed them for that and that, those of research papers, and now that they do the same imediately we're going to deny it?
If you do not trust Visa, then how about coindesk on how defi volume is inflated:

Now it's just a question of how much truth there is in that, but even if we assume that 90% is a bit of an exaggerated figure, I am of the opinion that the number of real users using cryptocurrencies (including stablecoins) is quite small compared to what companies like Visa achieve.
Well, all the transactions in the Bitcoin chain have surpassed the daily average on Visa, but we're not close to the peak shopping day...so...

Also, I don't know a single real life shop or pub that accepts USDT, I know 5 that d Bitcoin, so again, I'm pretty sure most of that tx are arbitrage bots playing between exchanges and markets, common, no sane user is able to do over 1000 transactions a month and why would he.
