1. We have a large homgoneous market where you can build a product and it’s expected it can succeed for hundreds of millions of Americans
2. EU is the easiest second market, and another step change of hundreds of millions of customers in a somewhat unified market
3. there’s not an easy 3rd economy that replaces EUs wealth, population, and comfort with English + technology
When we piss everyone off in the EU tech company growth gets kneecapped and limited to US / Canada. Theres not an easy market to expand to without much deeper focus on that specific market and its needs, for much fewer returns.
There's a strong desire to forge closer links with the EU now and reduce dependence on products that could be weaponized against us at any time. Geographic proximity doesn't count for much when it comes to software.
Unfortunately Blackberry was heavily dependent on US telecoms and corporations buying their servers and devices to pad their profits. And since then, local engineering talent from the Kitchener-Waterloo region has been siphoned off by Silicon Valley money, mostly to craft elegant solutions to deliver more ads to your devices.
A lot of business customers bundle their business/productivity software with their phone and Internet services. Did you know you can buy Google Workspace and/or Microsoft Office through your telco? I was shocked to find out how many do this when I worked for one of the telcos.
Just like how consumers bundle their streaming services with their home Internet plans.
One bill for all the things is convenient.
I would bet it's the same in EU (but can't say for sure, I only have first-hand info about Canada).
If there was a real push to move companies away from these platforms, it would probably start there, mostly because the telcos are typically very government-aligned due to regulatory and spectrum concerns, and would get in line with government efforts to promote non-US alternatives, if they decided to.
Getting the majority of consumers to ditch their US-based streaming and entertainment is another thing though, I can't see that happening ever, no matter how at-odds the US and Canada become.
