You ASSUME it's okay to sell carts with a HASL edge connector because you never saw any problems with it. Wrong, the board will get grinded and the female connector will get coated in junk.
You ASSUME since all components in a C64 are powered with 0-5V that they also communicate at that voltage. Wrong, they use TTL level signaling. It doesn't matter anyways, PLAnkton runs at 3.6V specifically to ensure 5V CMOS logic level compatibility.
You ASSUME you can just grab any components you can buy on eBay (XC9536) put them in a product and sell it without possible consequences. Wrong, most of them are not RoHS compliant.
You ASSUME an XC9536XL will turn into a time bomb if it is powered with slightly more than 3.6V. Wrong, they can take up to 4.0V, I even tested some at 4.3V.
You assume if PLAnkton is powered with more than 5V, the increase will be linear at the CPLD's Vdd pins. Wrong, the power consumed by the module will increase in a non-linear manner for reasons clearly explained.
Finally, that specific quoted statement above is clearly reminiscent of the tweets of Donald Trump... you stick to falsehoods with tooth and nail.
It's not my job to give you a course in digital circuits... unless you pay me.
Added edit:
If I follow your logic, the 1541 Ultimate I, II and II+ are total crap because the buffers used on these cartridges (74CBT16211) lowers the incoming signals voltage to match the FPGA's voltage (3.3V) but it does NOT increase the outgoing signals voltage.
Just like me, Gideon Zweijtzer considers 3.3V signals to be TTL level compatible and so does TI:
