There are quite a few situations where running the (previously) open source core was a good fit for business problems which would become unprofitable if the enterprise license was used.

I got job interviews from the original Triplebyte that I almost took just from investigating it as a source to hire engineers!

I think this is the magic legal judo of the (L)GPL that makes it work. Regardless of your feelings about the license, it's extraordinarily clever!
Note that if the license said you had to, for instance, share x% of your revenue with the licensor, that's not part of copyright law either, but it's still probably a legal license.
Thanks!
