Penetration???

I thought it meant they would switch

Frr got me thinking either they didnt go all the way (i read too many stories to remember if they already went all the way) or they will switch. I doubt they're going to switch tho

i also thought they were talking about switching because otherwise it doesn’t make sense what they’re saying, but i hate when an author hints at a possible switch just to never go through with it in the end
