Bridgerton Marina Thompson

Im rewatching Bridgerton right now and my only question is why people hate Marina so much like all im seeing a woman who had to what she needed do to so she could have a good life aswell as her child. If you think about it Penelope and Ms. Feathering both did similar things that Marina did. All three of them are women doing what they need to do, to get ahead in a time with sexist ideals lol. (Sorry if there is any bad grammar)
