OTOH nowadays we are seeing how many Apache/MIT softwares are effectively moving to source-available, non-FOSS licenses because other companies took advantage of what Apache/MIT permit. I'm clearly not able to predict what would have happened if all those projects had used a CopyLeft license, but still one does wonder...
You see it on FOSS OSes for IoT and embedded devices, none of them is GPL based, rather Apache or MIT.
