Where is this obsession about the apex coming from. I guess its from the explanation the stewards gave for the penalty. There is no mention in the rules of a driver on the inside being obligated to "hit" the apex (even though the stewards do not seem to understand where the apex is).
According to the rules, Hamilton was clearly alongside Max on the inside. The rules, I believe, say that the driver on the inside has the right to choose the line but needs to leave space for the driver on the outside, which Lewis clearly did (there was 5 car widths of space on the left). Just look at all the previous battles between the two where Max was on the inside (Imola, Barcelona, Portugal and Silverstone in Brooklands), Max leaves absolutely no space on the outside and serious collisions are avoided only because Hamilton understands that he has more to lose on the outside, something Max might learn from this incident.
