Easy...
You start out reasserting that 5e doesn't try to force one particular style of gameplay with its mechanics.
Correct. It cannot possibly do so.
Move on to dismiss description of how it does that by declaring that someone cares too much about the thing in question while pushing for that one style of support it offers.
No. There was no dismissal of any description of any "one true way." I did say you care too much for predictability, but predictability is not forced in the mechanics, nor is darkvision any more or less predictable than light. So if you think darkvision and light somehow force predictability, then every RPG "forces" the same "one true way" of needing to see things.
Demonstrate that you have no understanding of common light sources in d&d like the previously noted torch and previously noted bullseye lantern differ from modern day flash lights
I demonstrated that continual light and light spells have been there and used from 1e on. I will also note the use of both torches and lanterns in 5e. So again, no real difference in 1e than 5e.
Go back and see comments about excessively generous hammer space carrying capacity. 5e differs from those in the fact that carrying them was a nontrivial problem and the fact that most PCs couldn't just ignore it in combat with dark vision if they didn't bunch up somewhat or have multiple torches out. Those earlier versions didn't have trivial unlimited light cantrip casting either either(4e maybe excluded) .
Same issues in 5e as 1e. Also, why didn't you just drop the torches or put the lanterns on the ground during combat in prior editions and just fight with light AND hands free?
Yes because you dismiss everything you are told thwarts a particular type of play or adventure and push the not so flexible 5e style as the only style there is.
Light isn't a playstyle. The problem here is that you are arguing something that doesn't exist instead of something that does. Instead of trying to redefine what adventures/campaigns are, and redefine what a playstyle is, just talk about the mechanics.
Does the light cantrip start at level 1 in 5e, giving trivially easy light? Sure. Did continual light start at level 5 in 1e, giving trivially easy light? Sure. Could you buy continual light coins trivially cheaply in 1e because of NPCs clerics? Sure.
So explain why you think it is somehow bad to get trivially easy light at level 1 in 5e, instead of level 2 or 3 when you get gold in 1e is bad. Argue the mechanics, instead of some mythical and non-existent "one true way" of 5e.
Wotc even admitted that monsters aren't up to snuff... Having death saves healing word self recharging magic items trivialized resting for excessively generous recovery and so on plus those inept monsters makes for extremely overly durable PCs that clash with certain styles of play & adventure.
Bad monster design wasn't one true way to play, either. DMs can and did make up their own monsters, buy 3rd party monsters, or add additional monsters to fights. You weren't forced to play one true way of encounter design and have bad fights.
