Those arguing against the points in the OP seem to be following a goal of making Free software successful at the expense of commercial software. That strikes me as wrong (both in terms of efficiency and in terms of ethics). We want Free software to succeed. If it succeeds at the same time that other commercial endeavors succeed, then that makes the software ecosystem richer, and gives us a broader set of tools and ideas to employ.
