Agreed. I'm in the market for an imu and thought "ah the MPU 6050, I've heard of this one a lot even recently" and it's obsolete. This is typical of consumer to adafruit/sparkfun/aliexpress levels where they have countless old stock of cheapy proto boards to buy from, but if you're designing a whole new thing from scratch, that's inexcusable.
but i guess they used it due to existing code/drivers widely available for it and esp32.
