Pure open source doesn't seem to exist in this decade; all large enough projects seem to die without corporate sponsorship.

It was already like that with the projects that hit big.

Linux got lots of contributions from companies that would rather invest into it than paying UNIX licenses.

Eventually it got lots of support from the likes of IBM and Intel, because its existence suited their business.

GCC got lots of support when UNIX vendors started charging for their SDKs and smaller shops invested into it.

Likewise for many other projects.

Of course, most good opensource have a corporate arm behind them, which helps fund development.

Perl is thoroughly alive, large and not excessively corporate sponsored. Then again it's largely on the backchannel at the moment.
