I don't necessarily disagree, but you're glossing over the trade offs in making those decisions. Windows is a poorly behaved proprietary operating system from an extremely poorly behaved company with a long history of doing questionable things. OTA TV has ads and I presume lower quality. Checks, as we are discussing, have what appears to be some long-standing security problems. By all means is the best tool for the job, but don't mistake "works (ignoring costs aid side effects)" for "best", and please don't assume that just because people are very picky about what they use means that they're not doing so for legitimate reasons.
