Only 2000 people are moving from HTC to Google, according to the article. HTC will then leave the phone market. I expect Google to continue following Apple's lead and remove more features. They also have to try to stop their IP from leaking out, and go through some culture shock working in Taiwan.
This is an opportunity for investors to hire the other HTC staff who refuse to join Google for ideological reasons (open designs, repairability) or who just didn't get hired. There's probably a few other people from iFixit, WebOS, Fairphone hanging around here.
YC Summer 2018 is open. I'm in Taiwan. Who wants to make a business plan?
