That's where you're going off-course I think: Their responsibility ends when the Universe changes -- they have no control over such things. The best example of this, for you, is when federal law changed the parameters of DST, for the first time in decades. The DST problem was
not an existing bug, at the time that the S1 was moved from routine support into end-of-life support, and so it was not reasonable to expect that a fix would be forthcoming when the government threw a wrench into the machine. Another good example is SDV -- another external force that affected the utility of TiVo
without TiVo having any control over that force.
It is really important for consumers to ground their expectations in what is reasonable
for society rather than for themselves, and it is not reasonable for society to impose an expectation that a product manufacturer will upgrade a device that worked fine as it is when it was sold but through forces external to the manufacturer no longer is as useful as it was. If you want satisfaction, in such a scenario, try to get it from the external force that messed things up for you -- it's their fault, and so their responsibility if anyone's.

It absolutely does
not explicitly imply anything significant in that regard. It is simply a financial analysis for the reader to consider and factor into their purchasing decision
along with other considerations (i.e., how likely it is that the TiVo Premiere will be useful five years from now).
I can give you some idea of my personal experience. I divide utility into three categories: Full utility, limited utility, and no utility. My S1 provided full utility for two years and (very) limited utility for six additional years. My first S2 provided full utility for three and a half years, and a pretty high level of limited utility for three additional years and counting. My second S2 provided full utility for less than two years and
no utility since then. My S3 has provided full utility for almost three years, so far.
YMMV.
