Every platform nowadays is a way to lock you in. Strava makes exporting data exceptionally difficult and has API rate-limits. I’m sure there’s a technical reason, but still sucks.
One of the tech journalists I follow has advocated the need for legislation for data portability to avoid shenanigans like Spotify has. Much like the phone number portability in the mid-2000s or interoperability after Ma-Bell AT&T was broken up, it sometimes takes legislation to enforce an open Internet. I think GDPR was one of the first steps towards that.
