I'm not sure what you mean by the last sentence, but despite rumors, Facebook has not bought Opera. I highly doubt Google would punish Opera because they might be bought by Facebook.
Opera is not open source, they distribute only binaries. If the new buyer stuffs it with rubbish you don't want, there's nothing you can do about it other than switch. Might as well switch to chrome and learn to use chrome's developer tools when I'm not in the middle of something.
Of course, I will continue to test anything I make on Opera, it's just been dropped as my primary browser.
