Instagram -> Bibliogram
Reddit -> Teddit
Most or all have numerous hosts and you can pick the one(s) that are most convenient or memorable to you. It's also possible to host these yourself, and I've suggested in the past that HN might consider doing so for Twitter specifically. Reddit possibly as well. (The others are fairly low-traffic on HN.)
Quora would be a nice addition to the list.
Chrome/Android doesn't suppport extensions.
Normalising use of alternatives in links and the like (which privacy-redirect may well do) also helps raise awareness and profile of the alternatives.
That said, thanks.
