No, a similarity between SARS-CoV-2 and other coronaviruses was expected but not this. Flu is not caused by a coronavirus. From the paper:

This finding is in contrast to multiple published studies in which pre-existing T-cell immunity is suggested to arise from shared epitopes between SARS-CoV-2 and other common cold-causing coronaviruses. However, our findings suggest that SARS-CoV-2 reactive T-cells are likely to be present in many individuals because of prior exposure to flu and CMV viruses.

I'm not sure about the accuracy of this quote. In git world branch names have nothing to do with repositories. If anything, the "source of truth" repository is generally called "origin".

Who do you charge when the brakes don't work on your car? When the airbags don't activate? When your rain sensor doesn't work?

Believe it or not, your car is not that primitive when compared to a self-driving one in terms of the number of things it does autonomously.

Google Search is inextricably intertwined with news and publishers do not voluntarily provide their content. On the other hand, publishers willingly choose to post news on Facebook, as it allows them to sell more subscriptions, grow their audiences and increase advertising revenue.

This is technically not correct. Publishers can opt out from Google Search if they want to, so one may also argue that they willingly choose to be on Google as well.

If you can get people to buy/use it (like BTC, ETH, and countless others did), yes it would be.

The number of coins is just a definition. Bitcoin has satoshis (similar to cents) that represent one millionth of a Bitcoin. You could have defined it such that Bitcoin is actually a single coin worth $1T, and BTC is 1/21,000,000th of it.

Are you suggesting that all miners with renewable energy resources are located in the middle of a desert?

Even then, we could have used the equipment (solar panels, wind turbines, etc) for something else. Unless the world is running on 100% renewable energy it doesn't make sense to say that something that requires energy doesn't cost (the world) anything because it's running on renewables.
