People get upset about Loaded dice because it doesn't deal with the problem of the bad RNG. It's a crutch that they've added to help you ignore the problem (while calling you a cheater for not wanting to deal with their poor RNG) instead of fixing the actual problem behind the issue.
And no, I can guarantee that not a single one of all those people on Steam gives a single bit about good changes from 5e -- such as potions being bonus actions to use -- they only care because the most glaring examples of additions are things that make the game worse, such as it being too easy to get advantage in combat, classes robbed of their defining class features without getting anything in return, or height advantage effectively granting you both a +5 to hit and a +5 to AC, or HP-targetting spells like Sleep not being rebalance in proportion to the higher-than-average HP they've given enemies, and so on. It's not "it has to be 100% 5e in all matters" it's "this would be better if you just had stuck to 5e".
