"If you want to make money writing software, pick a standard proprietary license. There's no shame in that, and it's a much easier way to build a business than with free software or open-source. But if you do decide to make software open-source, then I think a copyleft license is best. Open-source (or Free Software) is a philosophy. It's not a business model."

I think many companies do think it is a business model. They are looking to get free labor from the community. History points to many anecdotes of community made software or efforts co-opted by a company. Usually ends badly though. Copyleft is the one way to not have your work co-opted by an entity looking to leverage free expertise and labor. It does put a damper on making money off your own work. Hopefully, though with efforts like flathub we can have both.
