Everyone in the cryptocurrency community has been ranting and raving about "mass adoption" since the beginning, but when it actually starts approaching people seem to want to run away.
Governments and global corporations showing interest in Ethereum does not mean they will in any way actually invest in it. In most cases they are developing private chains to convert their own currency into a blockchain based digital currency like we are seeing in countries like Russia, United Arab Emirates, and China. However, the reason they are looking into Ethereum so much is because many of these new digital currencies will be interchangeable with ERC-20 tokens. Ethereum will always be independent.
