We live in a tech world where it has become normalized that perfectly functioning software that you used to buy once and then got to use indefinitely suddenly receives an "update" to put previously existing functionality behind a pain subscription. The reasonable expectation people have is that an update fixes security bugs and maybe includes a few optimizations.

So no, I don't think it's a weird trend at all that people start describing software as "silently" doing things when trust in automatic updates of software (a thing that software silently does) has deservedly gone down the drain in the last few years.
