General idea is to make MVP webapp and then give free user accounts till you get traction.

I for one have been using a Honor (Huawei) phone for over 3 months with DNSFilter app running 24x7. Blocked all google domains after I installed the necessary apps from playstore. I don't see any problems if google shuts of Honor/Huawei devices permanently. I'd say it will be a benefit of Honor/Huawei phones. It will be the most privacy friendly phone out of the box.

Edit- I use Newpipe instead of Youtube. So thats the alternative for the last google service I'd need everyday.

I tried to do the sales tax management myself but ended up with incorrect calculation on some occasions. I would highly recommend getting a professional tax consultant for guidance. They'll know how to handle tax for your project. Once you start making revenue, the cost of consultant would become affordable.

I am in a similar situation but I already put my notice. What I did was speak to my manager and then speak to the founder. Both of them agreed that I should take the new opportunity and move on. Go ahead and talk to your manager/founder. They'll not feel threatened. They will support you with good advice.
