^A firmware update is coming soon, but according to the rumor it will add "Increased record time limits (but don’t expect a huge boost)".
My guess is Canon intended to cripple the R5/R6 higher end video modes but got carried away. They probably intended to give the R5/R6 the published record times for higher end video modes (and nothing more), but didn't fully optimize the firmware cripple since such things are a bit hard to get right if you are in a rush to release the cameras.
If this "firmware fix" that Canon rolls out only allows for the published record times and nothing more, then I still think the R5/R6 will be terrible for hybrid shooters.
Moreover, we shouldn't be supporting a company that is so clearly crippling its products all in the name of product segmentation.

The problem is I don't think Canon is going to "fix" the issue since it was never really a problem for them.

Canon Rumors is reporting that the rumored firmware is going to do the following:
Addition of Cinema RAW light option to 8K recording Addition of CLog 3 Increased record time limits (but don’t expect a huge boost) Various bug fixes They are probably going to increase the record times to match the stated record limits that they published but not much more.
The R5/R6 still won't be great for hybrid shooters since the published record limits were really short.
 

I suspected Canon to cripple this camera somehow, someway but this artificial heat limit and recovery time is really out of line. Such arrogance!
But you know what? Canon may think they control the market but we have the power to control them by boycotting Canon. Especially nowadays with the camera industry bleeding as it is. Force Canon to stop this BS. How?
If you already purchased the camera, return it. If you have it on order, cancel it. Cancel all orders with Canon. Write letters to Canon showing your disgust. Call Canon and voice your disapproval. Fight Canon with your pocketbook. Stop the BS.

It feels like the industry as a whole has some kind of collective Stockholm Syndrome with Canon. Why do we want them to be better? Why do we want them to fix their clearly intentional choice? Why do we want to pay them money when they clearly don't care to earn it?
Sony and Panasonic have been pushing the limits of hybrids for over a decade and yet many people are still hoping and praying Canon releases a patch or a fix for the R5 & R6. If you put your faith in Canon, prepare to be disappointed. 

There are (rumored) RF cine cameras coming out, but if Canon could fix this overheating issue with a firmware fix, but doesn't then I don't see how anyone in good conscience could buy the R5 or R6.
These cameras are clearly being marketed as hybrid cameras. Canon could leave in the 30min continuous record limit to create some market segmentation.
However, firmware crippling the R5 & R6 to such a degree that they are unusable except for very short clips is unconscionable.

Shame.
These updated rumors sound a lot less tempting than the earlier one.
Looks like the R200 at $3,499.00 will be severely handicapped and the R300 will the better one, but at $6,299.00 USD it is a bit too steep in price for something that essentially just matches the specs of the A7sIII but isn't Full Frame or has IBIS and has an RF mount and internal NDs.
