USA aid is very important to Ukraine, but even without it they would continue fighting. Ukraine has been without USA material aid for months already in the past, when the republican party was blocking it. And as it turned out, Ukraine sustained higher casualties and had less offensive power than with USA aid, but they were never close to folding.
Ukrainians + their supporting neighbours are very motivated to not be occupied by Russia, so they’re not going to just give up if Putin’s stooges come to power in the USA.
I’m absolutely certain that it wasn’t ads that put a firm like TomTom on a downward slope. This was actually the first time that I’ve heard someone proclaim that ads are the reason.
If your business is to sell maps + navigation devices for money and then the times change and now nearly everyone already owns a smartphone with built in gps + some car manufacturers provide sat nav as a default + another company is giving access to a map away for free, well then your business is in trouble.
I’ve never even heard of ads in TomTom or Garmin, since I stopped using a dedicated sat nav once I had a smartphone, but it wouldn’t surprise me if it was one of the things they tried to stay afloat after smartphones became ubiquitous.
