You are putting your own interpretation onto the findings - nothing in that research stated that masks were ineffective, largely or otherwise; it states they could be "less effective" if not fitted properly.
Two different things.
The study showed that surgical & fabric masks kept between 65-80% of particles outside the mask - that is not "largely ineffective".
Anyway, instead of a study that involved 7 people, how about one that involved 350,000 people?

Styczynski and her colleagues recently performed a study across 600 villages in Bangladesh where they provided surgical masks to some of the villages and cloth masks to others.
”When considering both types of masks together, we found a significant reduction in Covid-19. When we looked at each of the mask types separately, we found that surgical masks were especially effective in reducing Covid-19, though there was more uncertainty for cloth masks,” she says. “It may be that we didn't see an effect of cloth masks on Covid-19 because fewer people were given cloths masks. However, both cloth and surgical masks significantly reduced Covid-like symptoms, suggesting that cloth masks offer some protection.”
