Agreed, but I take the notion where there's smoke there's fire and apple needing to institute a repair program on the keyboard means something is inherently wrong with the keyboard. Will it affect everyone? No, I don't believe it, am I willing to take a chance especially given the price tag? No, I'm not. Others are and I respect theirs (and your) opinion but that doesn't negate that the 2018 MBP has an over abundance of reported issues.
Your assumption is just that, an assumption. The reason for the repair program could just as easily be an acknowledgment that it is cheaper to warranty a small percentage of laptops for an extra few years and increase goodwill among users than it is to fight a lawsuit that pits you as the big bad guy against the defenseless consumer and could drag on for years with huge legal fees. The repair program does not indicate anything about how widespread the problem is.
Also, what evidence do you have that the 2018 has "an over abundance of reported issues?"
