What kind of fantasy land do you live in that people replace their phone every two years and car every 3 years? You might as well lease a car if you are replacing it that fast.

This might be anecdotally true in your circle but if it was true for the market at large then every manufacturer wouldn't be forecasting major downturns in smartphone sales and the used car market wouldn't be so far upside down as there would be a glut of supply from people selling their used car every 3 years.

I think your points about privacy features, micro transactions, and headphone jacks are valid but I think it's a stretch to apply that to cellphones and cars and say that companies are against right to repair because of consumer attitudes. My observation is that the companies (ie John Deere) that have opposed right to repair are about protecting revenue streams from part sales and franchising/licensing fees and decreasing support costs from having to service products with non-genuine parts.
