For business, the copyleft is combined with proprietary license. So business gets "pro" version with no copyleft requirements, while open-source users get the same code under a different license.

And a lot of the companies mentioned in the article have moved to BSL, which _is_ copyleft (after a few years of delay), or to SSPL which is arguably even more extreme copyleft than AGPL.

It's misleading to call the BSL and SSPL copyleft, because while they are viral, they're not free.
