The statement: "Buy the Blus and you MAYBE get DS9 in HD" is not a fair deal.
I can understand that, but I don't think this should be viewed as an ultimatum from CBS or some kind of blackmail. From what Bill says - and judging by the sheer effort that's gone into these discs when other studios are bailing on extras - CBS cares about putting these shows on Blu-ray. What they need is evidence that further investment in Trek on Blu is worthwhile, and that's what the sales figures are.
You're still free to buy as much or as little as you want as a consumer, but Bill raises a good point that some fans don't buy the sets now that the shows have been remastered in HD. They might wait for a cheap complete series bundle a few years down the line, or for the HD versions to hit streaming services, not cognizant that purchasing the Blus sooner sends a signal to CBS. Enough signals = more Trek shows on Blu.
He's right to issue a gentle poke that if you love Trek in HD and want to see more of it, buying some sooner rather than later (or not at all) will help. Even if you buy one set on sale. If you already have them, buy some as gifts. Those guys within CBS who love Trek still need the evidence to give to the beancounters that this is an investment worth making. In that regard, they're our allies, not our unfeeling benefactors.
The other key takeaway from Bill's piece is that social media has an impact, even if petitions don't. That surprised me.
What if everyone reading this thread who has even one Trek TV Blu-ray set took a photo of what they have and put it on their Facebook and/or Twitter with the hashtag Bill suggested (#ds9onblurayplease)? What if they got every Trek fan they know to do the same? If word spreads widely enough, who knows what'll happen?
Sure, we've already bought them and sent a signal that way, but let's turn our boring statistics into a vibrant image with a passionate comment attached.
What do we have to lose?
