When I worked in the scope shop, the owner refused to do business with them. He said he couldn't trust Diebel. The whole Crown Optics thing showed him that Diebel didn't care about the retailers or the customers, and was just in it for the money. In contrast, he felt that Tom Johnson, being an optics designer and amateur astronomer, meant that Celestron was in it for the users and the stores. However, he also observed that Celestron was not as smart about business and marketing as Meade, which was frustrating for him.
Meade did bring competition to the SCT business that Criterion hadn't. That kept Celestron from getting complacent. When Diebel returned to Meade, there was a big push to innovate, with the ED refractors and the computerized mounts, which drove Celestron to match them. (And there was also a fair amount of copying, e.g., with the eyepiece designs, Maks, etc.) By then, Celestron had also gone through a series of owners, and some bad years. Things turned nasty with suits, and they were trying to get ahead by bashing the competition. That weakened both of them.
So now we have to depend on Synta as an unregulated monopoly, which is never a good thing. Fortunately, there are still some independent manufacturers, especially for specialized and higher end equipment. But for most people, it means that a telescope will now just be a few different rebrands of one line.
I always saw Orion as another mail-order house that sold regular brands, sometimes regular brands under their own name, and also cheap accessories and beginner gear that they imported. Hard to say what was guiding their business model, which felt like it was flailing. I bought some of their 100mm table top dobs for the school after the Astroscan was discontinued, and a few odds and ends. They were a nice alternative, especially for beginners.
With OPT gone too, we are down to just a few online retailers. I worry that, with the internet and express shipping, Synta could decide to bypass their markup and sell direct. That could put them out of business, which would also make it harder on the smaller manufacturers.
Thus, I don't miss the business practices of Meade, but I do regret that their absence could reduce diversity and competition. And I will miss Orion as an alternative at the lower end.
