What it is, and why the name exists

"Blue matcha" is a brilliant bit of marketing and a category confusion, and the clear definition is the whole point: it is powdered butterfly pea flower, not matcha at all. Real matcha is shade-grown green tea; blue "matcha" shares only the powder format and the latte aesthetic, so the name borrows matcha's trendy, premium, whiskable halo and attaches it to an unrelated blue powder, see what is matcha. The single most important practical consequence is caffeine: real matcha is notably caffeinated, while blue "matcha" (butterfly pea) is caffeine-free, so anyone choosing it expecting a matcha-style lift, or avoiding caffeine and assuming all "matcha" has it, is misled by the name. Its genuine use is visual, and its health claims are the same over-claimed antioxidant framing as butterfly pea generally, best enjoyed aesthetically rather than medicinally, see tea myths debunked.

How to use it, and what the name distorts

Used for what it actually is, blue matcha is straightforward and fun: whisk the powder into hot water or milk like a latte, add citrus to trigger the dramatic pink-to-purple colour shift, and sweeten to taste, the flavour being mild enough that the appeal is overwhelmingly visual, see butterfly pea. The reason to spend the words on the name rather than the recipe is that the name is the only genuinely misleading thing about it, and it misleads on the two facts a buyer most needs: it implies green-tea matcha when it is butterfly pea flower with no tea in it, and it implies matcha-like caffeine when it is caffeine-free. Strip the borrowed word away and there is no controversy left, a pretty, mild, caffeine-free, colour-changing botanical powder that makes a striking blue latte. The one safety note is the cluster-standard novelty-botanical one: low-risk in normal amounts, but check local rules and ask a pharmacist if pregnant, medicated or unsure.
