Thank you for sharing and I am happy your computer works. But Apple must know that that is not a solution. If my computer worked, and then the only thing that changed is the upgrade Apple (eventually) forces you in to doing, and then it doesn't work. Then the upgrade or the upgrade process is broken. If there are known compatibility issues with software, your upgrade should do a pre-check to warn you - as every software maker used to do.
When did 'every software maker' do that? In the days of punched cards?
No, it is not Apple's job to test every piece of software for compatibility with a macOS upgrade/update. Apple provides many rounds of pre-release versions for developers to test their own software and ensure compatibility. If those developers fail to do so, that's not Apple's fault. As a user, it is your responsibility to confirm that any critical software you use is compatible.
Like @Barney-15E, I have had no performance issues with Tahoe (I have found some graphical bugs that were clearly Apple's fault as they were part of the macOS UI, for the most part those seem fixed in 26.1). Sure, that's anecdotal but it certainly supports the fact that it's your system that's causing your issues, based on software you've chosen to install on it.
How is Apple forcing you to upgrade your software? I have a Mac still on Sequoia, and I may upgrade it at some point but Apple certainly isn't compelling me to do so. The 'forcing' part ultimately will more likely come from 3rd party software, since major developers like Microsoft and Adobe (and minor but sometimes important ones like Intuit / TurboTax) only support the most recent three versions of macOS. Still, a person using those applications would not be 'forced' to upgrade to Tahoe until late 2028.
