Peacock's normal consumer offer is paid rather than fully free. In other words, Peacock is not something you should judge by the headline alone.
That headline answer is only useful if you also understand the practical limits. On Peacock, free or entry-level access usually means living with the practical question is whether its library is wide enough for your viewing habits, not whether you can approach it as a free service, which can be fine for casual use and frustrating for regular use.
