Trump doesn't stand for, or enjoy the support of, all conservatives. In fact quite a few of his policies and actions directly contravene long-held conservative principles, like free trade and staying out of internal business decisions.
The response inside Google was "I will keep hounding you until one of us is fired. Fuck you." And Damore was fired for the memo; the person who wrote those words stayed on.
It should be telling that after the fact he chose to idolize the KKK and proceeded to dox a bunch of Google employees for incredibly tame remarks in his class action lawsuit (of which I saw many images make the rounds in the alt-right media centralizing said information for obvious reasons).
Regardless his memo which he chose to release internally caused a massive divide among employees a Google. If Damore was kept on I imagine you would've saw a lot of talent proceed to leave the company. Additionally it's funny that you bring that up, considering there are a lot of people on the left that work at Google and feel like their views are being stymied.
Furthermore even if that had any bearing on their search results whatever google presents on their own damn website is also none of the government's business.
Also we should all want section 230 protection it's what preserves free speech online and the principle on which the whole web economy is built.
I think it fair to say that if Google wants to be a publisher, they should be held accountable to the content they publish. If they want to be a neutral platform, they should not favor any particular viewpoint
As for 'being held accountable' as publisher, I'm sure you're aware of many publishers that favor one side or one "viewpoint" in fact it's most of them, and they aren't being held accountable for that because we live in a free country.
The copyright stuff applies to everyone already.
