As a general idea: Very much, pretty much everyone around agrees that it's a good thing and 'we' should do it. When the choise would be slightly inconvenient for them personally: Not so much.
And obviously there's the few who actually use signal and fediverse, drop meta/google/twitter and make active choises when shopping for things, but there's not too many of them. Here in Finland we have markings on food which are domestically produced, but as very few pineapples or olives grow around here I don't think too many pays attention on where the products come from. And then there's chain labels like Coop which often label country of origin as 'EU and non-EU countries' anyways.
And I'm not any different, even if I consider to have pretty decent knowledge on things. On groceries things like Coca-Cola are produced locally even if the mothership gets their cut and with corporations like Nestle it's just pretty much a lost cause trying to keep up what brands are "bad" by some metric.
At least on digital world it's a bit easier, but there's still things like whatsapp and instagram which are important enough due to their massive user base that they just can't be ignored for various reasons. And with electronics I try to avoid at least the cheapest Chinese crap, both for quality and security (yeah, I know, not using Huawei phone to use Meta apps is a bit hypocrite). But I also try to stay away from Google services (but I'm not going to root my phone just for that), run Linux almost everywhere (but that's what I've been doing for 20+years anyways, it's not about country of origin), use Amazon only if there isn't alternative (or the alternative is so much more expensive that it just doesn't make sense in personal scale) and so on.
Maybe it does something, maybe it doesn't. I just try to throw my pennies in a hat whenever possible to keep things around locally. I live in a small rural town and if I need a can of paint or a single bolt I need to drive ~50km round trip to get anything. Should someone open a hardware store in here I would be the first customer just to show support. But I'm not made out of money either and have my limitations in life, so if the local business is too slow, too expensive, too rude or whatever else I'm not going to feel too bad when they go down. And that's the general idea I try to apply even more broad scope, whenever there's a "local" viable alternative I try to prefer that, just to keep competition alive and have more european base values around, but I'm not going to make my life unnecessary complicated because of that either.
