IF you wish to understand the answer to your own question, here is what I suggest that you do.
1 - qualify as a pilot
2 - land several hundred times and note the differences between the landings
3 - realize that landing is an art, not a science
4 - realize that all pilots sometimes land more firmly than they wish
5 - understand that the firm landings experienced are well within parameters & safe
6 - then get frustrated with ignoramusses who dont understand
