Both are true, now being very careful regarding software patents
usually pays a lot. Strange things happen in the legal world.

Some proprietary algorithms may perform even better and faster, who
knows for sure? And even if for now lzo or lz4 are better, we may find
something still better than what we think is now. In short, I still
tend to think that the right answer would be to have a dedicated set
of hooks and let people play with the compression algorithms they want
(statement stands for FPW compression as well, but that's separate
than the multivariate statistics patch).
