> Meanwhile jet fuel for private jets is (and remains) not taxed at all, even in the EU.
Not correct. Fuel for private aviation is taxed, including jet fuel and avgas. However, there are very few "private" jets, most are operated by some company, and therefore not private. Jet-A1 for a truely privately operated C172 with a diesel engine is taxed.
Full scale is unlikely. Russia could not, but they might send 250k/year to die in Estonia. EU and Nato (with or without US) would defend. But I doubt they would go all the way through Russia to force them to stop.
Nuclear option is not likely to be used for some "minor" conflict like that, because it would go both ways quickly.
Starting from the second note the brain switches to reative mode (at least a brain that got some relative recognition trained before) and no AP pitch will be memorized.
Ads are doing worse, not better. The purpose of an ad isn't to be clicked but to increase revenue. In the end of the year data will show clicks have gone up but other more important metrics haven't.
Who is guilty for tracking users? The site relying an income from ads with user-tracking, or the company buying the ads based on tracking instead of some less invasive method of distribution?
