Just a note about software

Despite I've involved myself to Windows Insider Program and many other beta-testing programs, observing really strange tendency:

many companies in chase of saving money completely moved testing to end-users (even for paid software).

Mean they do not test products at all (all good stuff like code validation or unit-testing or CI/CD - it's not about testing at all, it's about coding) and say to users "hey, I built something, spend your time to say to us if you see bugs and if you want us to change the product".

But truth is that as end user - I do not give a sh*t about doing work for you since you do not pay me.

Yes, it's a must to have developers <-> customers communication and feedback and support and voting for ideas etc. But if I want to buy something physical (like, I purchased musical synthesizer recently) - I will not ask HW company to change all knobs, test all features, it should work for me as I expected or give me my money back.

So why software companies force end users to work on them under the guise of flexibility and adopting to changes? Why just not do their work in providing well designed and tested products from the start?

Yes, there will be bugs, bad releases, unsatisfied customers, but also there will be some process that predictable in behavior as an agreement between what companies want and can deliver and their potential or actual customers expectations.

In fact: I have stable working software from 1999, I do not have any single stable working software product from 2018. At all. All new products (all types, standalone or web, and all products redesigned from legacy) have easy distinguishable serious issues. Easy to find in 1 minute of usage. Untested at all.
