Nobody is pulling a fast one on me when I buy my iPhone and Mac. I know full well what Google and Facebook are doing with my data when I use their sites.
I. Don't. Care.
They have products and services that I want and I'm happy to fork over cash or data to get them. Please take your conspiracies elsewhere.
But after China, the killer drones and how they are destroying other players for no other reason than greed and carelessness I don't defend them anymore.
I still trust them with my data in their cloud, for now, but I try to reduce their power.
If we are lucky they might even become nice again in the future.
They used to be wildly profitable even when they were nice.
In that particular case I agree: it might just be that the front-end devs at Google are seriously unprofessional or that their QA team is really understaffed or bad or something.
But I think I pointed to that alternative, just that I didn't find it plausible.
Reasonable alternative explanations for why the search results page would keep one core on my machine spinning up, but obly in Firefox or why there's always something with Calendar (but only in Firefox) might be accepted.
But personally, even as a one man team at the moment, I try to make sure it works in all browsers.
