Fine green, white, oolong, first flush and aromatic teas are prized for subtle sweetness and aroma that sugar flatly overwrites. Here "ruin" is fair: you are paying for nuance and then hiding it.

For strong builders tea: no, it is a preference

A robust CTC blend brewed strong is a different drink; sugar there is a long standing, legitimate taste choice, not vandalism. Snobbery about a sweet builders brew is unwarranted.

The real issue is masking faults

Sugar most "ruins" tea when it hides bad brewing, so you never taste how good the tea could be. The fix is better brewing, not a sugar ban, see the temperature guide.

The slippery part: habit

Heavy sugar trains the palate to need it, so genuinely good tea starts tasting "not sweet enough". That is the sense in which it can dull appreciation over time, see how to cut sugar in tea.

A reasonable middle

Keep delicate teas unsweetened to taste what you bought; sweeten strong everyday tea as you like; brew everything well so sugar is a choice, not a rescue, see tea without sugar.

Honey does not change the verdict

Honey "ruins" delicate tea just as sugar does, it is still a strong sweet overlay; the per tea logic is identical, see honey in tea.

In a sentence

Sugar ruins delicate tea and is a fair preference in strong tea; its worst role is masking bad brewing. Match the choice to the cup, not to dogma, see sugar in tea.

What sugar actually does, by tea type

The verdict is about the tea, not morality; read across the options.

Sweetener	On delicate leaf	On strong builder's tea	Note
White sugar	Masks the character you paid for	A harmless preference	The verdict is about the tea, not morality
Honey	Adds its own flavour, still masks	Pleasant, changes the profile	A flavour decision, not a health upgrade
Sweetener	No calories, often an aftertaste	Workable if you dislike sugar	Solves calories, not the masking question
Unsweetened	Lets the leaf speak	How most tasters drink it	The default for tasting what you bought
