Microsoft and Apple spent tons of money to make theirs what they are today and we didn’t
Not personally, but there’s loads of companies that work and contribute to the kernel and all the surrounding software, they give funds, obviously not as huge as Microsoft’s paycheck, but with less I’d say we have achieved way way more in several aspects, application support is entirely on the devs, be it Microsoft (again) or Adobe or what have you, yet we’re able to run alternative suites that are at least an 80% of what those proprietary options offer, for the office suite in particular I think we’re pretty well off with Onlyoffice.
Money, though important, is clearly not a measure of quality in software
