FYI:

I have just gotten confirmation by the author that Facebooks zstd
compression library is now a pure BSD license without PATENTS protection
claims which Facebook also removed from ReactJS and graphQL.

This means that zstd it could be a viable compression technology, for
example in QUIC/HTTP - though I haven’t followed the HTTP efforts closely.

zstd appears to have the best tradeoff in terms of
cost/bandwidth/computation effort while I personally would use LZ4 for some
performance critical applications to due raw speed where bandwidth is
sufficient.
