Uh.... unless you’re in the EU the warranty on the battery is one year. Not sure where your claim that a technical fix to stop shutdowns is somehow really to prevent warranty battery replacements, but go ahead and conflate away...
Wrong. It's not just EU, and wrong that everyone else just gets one year. If you are going to hit others up for data, please don't be so wrong about the facts.
I suggest you have a look at consumer laws globally, your assumption is wrong.
And even if it was just the EU...... kind of a large markert to avoid warranty replacements? conflate away , as you say
