Well, yeah. I was talking about besides the actual terms of their agreement.

and how hard is it to change that? as hard as it is in edge?

Firefox has pretty rich search settings, better than any other browser IMO. It's very easy to use different search engines for different things and changing the default is one click in about:preferences. As easy as it gets I think

That’s an arms length business arrangement though, rather than some undue influence

Its hard to be truly arms length with the person who gives you the majority of your money.

Well, at this point we've degraded into vague speculation, which isn't up to the standard that should be necessary to guide people's decisions.

If new scary stuff starts showing up in Firefox of source code where the auto sign you into google, or strangely start turning away from web standards and towards Google supported proprietary initiatives, or something like that, that would put some meat into the nothing burger.

If its hard, then they they must be commended for doing so.
