My comment wasn’t written with enough precision.

Using GPL software: yes. Totally fine. The rise of Linux and all that jazz.

Incorporating any part of GPL software _into_ other products? Pretty much doesn’t happen. Every company I’ve ever worked for has said “do not bring LGPL or GPL software into the codebase.” When it comes to commercial software, be it cloud based, or downloadable, you’re not going to find much that tries to incorporate GPL stuff. You just won’t.
