"Smart" home gym equipment: expensive hardware for some grand, proprietary software, and ongoing subscription fees in the $50/mo ballpark.

The SW is usually designed so that even shit that could have been local is instead stored remote as to make the subscription look more worthwhile. The large front-up cost serves not only as revenue, but also to anchor the vendor lock-in.

Open source hackers could potentially unchain the HW so that users would actually own what they purchased, but there is a catch: the HW is sold at a loss, and the subscription is the business model.

Freeing up the HW would render the subscription rather useless, and ramping up the HW sales prices to profitability would destroy any demand.

Basically, it's products that are technically feasible, but not economically viable. Which is why they are not the future of home gyms.
