Good for you. Feel free to discontinue one of your domestically most popular product lines to save costs. After all, it’s your busyness.
One production line and three products. It does sound like you run a busyness, not a business.
Canon’s business is worth >$30B and spans a wide array of industries and product lines. I suspect they know just a little bit more about how to run a business than you do.
As a matter of fact, the new insight from Canon is that the stop developing the M line. As they did to the D line and EF glass.
There is one thing to be happy and wish that things we like will continue to be made into the future, than busyness decisions companies are doing despite our own wishes. Did you see the note saying canon abandons the next M series camera? Canon does not follow OUR wishes and our "logic". They sold thousands of EF lenses, if they follow your logic, they won't stop doing so, but they develop mirrorless cameras, with new mount, and from that point they stopped making EF glass, despite my own wish that they will replace, for example, the 50mm f1.4 ... I wished they wold make 32MP 7D mark III, but they didn't, why, cause someone in Canon made the decision FOR CANON. And since an APS-C RF camera is going to happen, the M class which is exactly the same thing, seems, even to Canon, something they should not continue manufacturing. As much as the AE-1 was successful, and for years it was the best selling camera canon ever made, when they change to EOS cameras, and EF glass, they stopped making it. You can continue to argue that the M line was the most selling product, but, according to Canon, the M days are over, as they did to the EF, and FD before.
Time changes, you can't relay on the past to continue. And as it seems, Canon decided to stop the M series.
