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.
In 2022 there were some stories of how people on work visas were unable to jump ship while others were fleeing en masse. And now after all the tech layoffs in the USA, I imagine that finding another company to sponsor their visa, has become a lot harder still. So that’s one group still working there: people who will be deported if they lose their job.
