Just one data point and my usage may not be "pro" the way broadcast or film would be (I've done mainly in-house educational videos for a couple of universities).

We went from Avid in the early/mid 2000's to Final Cut Pro on Mac Pros (in the cheese grater days) to Premiere Pro on Windows workstations which I still use today. First we switched away from FCP when Mac Pros languished and FCPX tossed out a lot of the features we needed. I understand that a lot of those were later replaced but at the time it was a dealbreaker.

With Premiere, we can edit on either MacOS or Windows workstations, performance is good on a properly equipped machine, and it integrates well with the other tools in the suite like Audition, After Effects, and their still-image stuff like Photoshop and Illustrator when needed.

It's not going to work for everyone and I'm still not a fan of the subscription model (much prefer the old way where I'd spend $600 or whatever every few years and be done with it). That said, it doesn't surprise me to see it getting professional use, just as it doesn't surprise me that other production houses find FCPX to be a better fit for their equipment and workflow.
