End of story? Maybe in your emotional ego driven thinking. Until anyone offers proof that delays are due to anything but demand and supply chain, these conspiracy theories are useless.
Yes, not planning for unseen circumstances is unforgivable. I mean, it is fine that you personally didn't plan on the unknown and sold your camera, but not ok for Canon to have unexpected delays right? They must be made accountable, but not you. They should be held to the fire for not planning on unknown supply chain issues in a pandemic and they should always have perfect prediction of demand. When Canon has an issue it is a failure they are hiding, but when you do something blatant to cause yourself an issue, blame Canon?
Nice how you call a pandemic not a good enough excuse. What would be good enough? Have you never heard of demand on any other product, seriously? There have been plenty of things that people have to wait to get when unexpected demand or supply issues happened. Your complaint seems a bit self centered and naive. Hard drives, game consoles, TVs, cars, the list goes on and on of things that have had long delays before due to all sorts of issues from tsunamis to weather to market forces. Even if Canon is fixing some problem in quality with the R5, saying so would not get the cameras out faster and would only inflame the internet trolls to even louder heights.
Anyway I guess I will go shoot with my 5D4.... since Canon is doomed I better enjoy it until the internet tells me it is worthless.
