The sentiment around buying European/Canadian alternatives to American products and services is a great one, and I can get behind the movement, but there is more to it.
Not all products and services have alternatives that are viable. You can’t get your workplaces to move to libreoffice or get your mom to start using signal messege. Moreover, even when using Europa products and services you still perpetuate the culture of uncontrolled capitalism and enriching tech billionaires. Open Source Alternatives, Piracy, and Ad Blocking are all equally viable.
Keeping this in mind, remember that piracy and ad blocking are great ways to keep using American services without contributing to their bottom line.
There are ad free versions of YouTube, reddit, Instagram and Facebook apps. They’re all patched with revanced and are available on github.
Additionally, pirate media as much as you can and be unapologetic about it. Facebook is doing it, so can you. Pirate music, movies, books they’re all available. Torrents community has never been safer and better organised.
Consume without paying and that does more damage to their bottomlines.
It’s not European, but if one is simply looking to avoid buying American, Toshiba is an option.
Likely more options as well if one looks at the SSD market, but I am assuming there may be a reason you’re looking for an HDD specifically?
As @remon@ani.social says, they’re too expensive per TiB
There’s two European manufacturers of SSDs, Wilk Elektronik in Poland and GS Nanotech in Russia.
Unless you’re shitting money SSDs are not really viable for mass storage.
