Can't speak for this forum, or indeed how paladins are in 5e, but fwiw:
As a DM and armchair game designer, paladins trigger my itch to fix the system, because they're kinda cool but restricted to one alignment, and in many published versions quite a specific way of playing that alignment and a general attitude. I always want to create Holy Warriors for other alignments and philosophies.
I know several players (the kind who 'usually play Chaotic Neutral' who dislike do-gooding Boy Scout types, especially those they have to share a party with who cramp their style. Paladins have 'do-gooding Boy Scout' tattooed on their foreheads, in many groups.
Paladins in 5e are not restricted to the Lawful Good alignment any longer, they can be any alignment they like. Though I have seen a lot of people still making LG paladins, because this is how it used to be, and some GM;s still make it this way in their worlds.
