Flash had lots of issues, but it certainly enabled artists to make really interesting sites, sometimes with very limited technical skills.

Dang it. I had forgotten that most debit cards now have partnerships like that.
However, remember that debit card transaction fees are typically quite a bit lower (no exact numbers to support my claim, but for instance my hairdresser only takes credit for larger payments; small ones she only accepts debit, or she would just lose too much to the credit card company).
So you wouldn't NOT support MasterCard/Visa, but they WOULD receive less money.
As for non-American credit cards, someone asked a similar question on Reddit and got technically valid but unsatisfying responses.
For instance:

Like, when they say "don't encourage the US" people don't typically mean jumping to Chinese companies instead. Not to mention UnionPay is definitely not as widely supported as Visa or MasterCard.
And while Japan isn't exactly notorious for its human rights violations these days, I kinda doubt JCB cards would be very widely supported. And could you even get one if you're not Japanese?
Do you get the pop-up about on your phone about having plugged in a device to your phone? Have you tried a different, seemingly less preferable option?
I remember I had a phone where I had to choose an option that didn't seem like the right one at all for my PC to see it.
Also, do you have another PC/OS installed? Just to see if you can eliminate variables.
Unless your income is really low, look into FHSA. It's a stupidly advantageous investment mechanism. It's like RRSP in that it reduces your taxable income, except it doesn't become taxable when you use it. (Although you can only use it for a real estate purchase.)
As for investing in Canada, lots of banks and financial advisors offer managed Canada-only investment funds.
Personally, I just go for socially responsible funds anytime I can. Lower returns, but it doesn't tend to crash as much as the general market when the news talk about massive market downturns, and above all, it doesn't come with the guilt of investing in weapons or fossil fuels. And well, even if it's in the US, I really don't mind investing into a company that's not morally terrible.
