There are quite a few people who take that view.

The line itself (from Gerson) is "Legend has it, an 'angel' who has seen the surface will descend from above and bring us freedom."

Technically, that could refer either to Frisk or to Asriel. Both have seen the Surface, and while "descend from above" fits a bit better with Frisk, Asriel did return to the Underground. Asriel is the one who directly destroys the Barrier, but Frisk is the one who ultimately makes the whole course of events possible, and the line is simply "bring us freedom" rather than "destroy the Barrier." So either could be a viable explanation.

I think a lot of people tend to side with it being the protagonist because of the next line, which goes "Lately, the people have been taking a bleaker outlook.../Callin' that winged circle the 'Angel of Death.'/A harbinger of destruction, waitin' to 'free' us from this mortal realm..."

That fits better with Frisk, and doesn't fit with Asriel. If the Angel is supposed to represent a single entity that could "free" the monsters in both ways, then Frisk (along with Chara) represents the best interpretation.

Of course, they could be two different entities. Perhaps Frisk is (potentially) the evil Angel, and Asriel the good Angel.
