I do think it's part of many people's vocabulary. It's a bit informal. And it's not a word you use every day. But it's definitely a word that gets used when the occasion calls for it, just like the related verb "verschlimmbessern."

"Enshittification" isn't the same thing. "Verschlimmbesserung" is when you try to fix a loose connection in a power cord and then no electricity flows at all, or when you try to fix a bad haircut with a trimmer and the haircut ends up looking even worse, etc.

It's certainly used - not in the top 100, but if the situation calls for it, it's not unexpected.

There's a big difference between enshitification and "Verschlimmbesserung". The latter has the intent of actually improving things, while the first is making things knowingly worse for profit.

Of course it is still widely used.
