I think the most common tech term is "depreciation". Tor should be o marked on their boot page but that assumes there is a practical replacement.

Also unfortunate that, today, one of the few places still
propagating such blankets, in reverse via false advertising,
downplaying, failing to mention, etc... is the Tor project itself,
not least where is on its very own front page.
Attacks on today's overlays may not be exactly cheap
fast easy or wholesale, but they do exist and are in use.
There is no project today that should not at least
be putting a link to such warnings and docs...
on the front page, download page, in the app, etc.
And no reason that when designs and efforts thought to make
existing attacks a significant factor harder... upon their startup
10, 15, 20 years ago at that time... whose fundamental
underlying technology is now matured to point of diminishing
returns on investment against continuously advancing attacks...
should not be marked and understood as such by the entire
overlay community, so that new fundamental treatise
are naturally encouraged.
