Yup, some people are just dumb. I am tester for living so using preview build is fun for me. I am sending feedback to MS, but I do have it on my daily driver phone.
I am able to provide best feedback from daily use. I rolled back only from the first Redstone update as it was totally unusable as daily driver.
Yet I understand the meaning of this program, so I reported my issues and did not complain at all, when I had to wipe my phone.
Only one thing bothers me about this program and those are its rules - I accepted that these preview builds could actually destroy my device. This is the only thing that I do not like since I am using 950XL...
so I took a risk that this won't happen. At least I hope
Anyway, I really like this insider program and it is great when you see MS implementing stuff insiders wanted.
They of course have a legion of beta testers for free, but we are getting better system that we love as a reward.
Yet I would not mind at all, if they reward us with some special discounts on MS products..
