The liability scenario you claim will fix everything has already been the status quo in Android-land from the beginning. It clearly hasn't fixed the attitude OEMs have towards updates and security in thee last 5 years and other than outside pressure (Apple) continuing to make them look inept at update and support, I don't see any drive from within to fix the situation, and the Android-enthusiest attitude of "just put a custom ROM on it to fix your broken, abandoned product" only reduces the number of people who understand the problem and would be angry enough to file lawsuits or give bad PR a year after their purchase.
