Well yes, they obtained a majority by ensuring they poured all their resources into swing seats to convince those to turn away from the Conservatives, as I now restate.
Parties are there to obtain power under our system, not to convince voters whose votes are unlikely to be decisive so people online can meaninglessly crow about vote shares.
Labour in 2024 have 411 seats and form the government with a commanding majority. In 2019 they got fewer than half that number of seats, having lost to a bloviating dullard playing out a World King fantasy, subjecting the country to another five years of Conservative rule.
If you do not think that is a good result then that is up to you I guess.
