No, this is incorrect.

The USFS does a lot of controlled burns, and has done them for a long time. Not sure where you heard otherwise: it's a significant part of what they do.

They briefly paused doing them last year after a controlled burn got out of control in New Mexico, resulting in a high-profile wildfire. But that's only evidence that they were already doing them. Anyway, after updating their policies, they resumed prescribed burns later that year.
