VPNs are not the type of consumer product you EVER want to have acquired by ANYBODY. Not by Google, or Facebook, a US company, a Russian company, a Japanese company, NOBODY. Was this not extremely obvious when the deal started to form?
You've made a lot of promises that nothing will change, but those are empty promises given the history of post-acquired companies, as well as the vpn market as a whole. You have a lot of work to do following up on those promises, and until you do you will not have the same level of trust as you once did.
