A $100 scale isn't really that captive, especially if continuing to use it costs that much per year. There's no shortage of scales for tracking weight loss and the Apple health integration in my Withings is pretty useless from experience.
I am really impressed with my Apple hardware but the services strike me as uniformly shoddy and dare I say a lifestyle brand that seduces people into treating garbage as if was gold. Ok, I like what they did with Foundation, I really do, but I think Apple Health, Apple Home and all of those things are for suckers and Withings probably thinks so too. For all I know Apple is charging them an arm and a leg to participate. On the other hand, Garmin Connect takes my active lifestyle seriously.

I'd probably prefer a second more fitness dedicated watch otherwise so that data integration was better.

The official charging cable is atrociously unreliable, enough that I almost gave up on the brand, but there are numerous third party charging attachments like

from Chinese brands with weird names that work perfectly.
However, once you're within a system, and used to interacting with it on a daily basis, you would lean towards their slight nudges and pushes, and over time subscribe to a $2/month service, or their "new solutions" etc.
Not to forget their continued advertisements in the app, and constant pushes. You're no longer a customer that purchases a product, but instead a captive audience that is constantly being engaged and steered towards one thing or another.
