They are being downvoted because "make as much money as possible" is not a clear cut proposition. Apple ran (runs) an expensive recycling program and investors complained that it wasn't valuable at annual meetings. Steve Jobs said "We disagree" but he wasn't replaced. Lots of companies don't maximize the dollars out of every single thing, in response to a bigger picture / longer term vision, and it's up to leadership to sell it to shareholders.

Etsy could certainly argue their bottom line in the long term will be helped by curating a higher quality marketplace and getting rid of junk sellers, if that's a problem.
