Correct me if I'm wrong, but by the same logic, you could also say this whole containerization framework is of no use either.
If they're investing resources into it regardless, they might at least try making something that Docker for macOS and co. haven't solved the same exact way already. Something that, due to their almost unhealthy obsession with "system integrity", only they can realistically make. Like native containers.
Supporting the containerization framework lets them sell more laptops to Linux devs that may have otherwise bought a Dell or hp or insert brand to run Linux natively on or windows with WSL.
Containers are REALLY REALLY popular. This is a a great value add for developers on Mac who need to deal with Linux containers.
Which is a ton of ‘em.
