Seems to be in line with BMW's enshitification moves they've made regarding Home Assistant. I actually have an X5 that was affected by this & it will be the last BMW I ever own.
I don't disagree with you on BMW's data collection capabilities. However, I've read about 2023s being tuned. It's also widely reported that BMW encrypted many of the computers starting in 2024.
This past September, BMW disabled 3rd party access (think Home Assistant) to vehicle data. There are only 2 paid 3rd party companies allowed. 2+ years of me using HA (with some awesome automations) was terminated. I was willing to let them use my data as long as I could too, but now I don't even have access to my own data!
