It is funny how some are saying that its such an old quote while completely forgetting that this change did not happen recently. So yes somehow they went back to their words in a quite short amount of time.
The problem is, that having to go into your house every 45 days does not mean that you are using it a lot. Workshops only work for FC, gardening wont be done in the break either and nobody has a list of what you need to do with your house to keep it. I for example sometimes use the garden plots but I did not buy it for that. I just like to decorate and craft my stuff but you also cant always decorate because of the limit and because you wanted a certain look. So I have used hours to decorate the FC and private house but right now its done thus I use it mostly to craft in there in peace and to have a nice little spot to visit. So with your list I should lose the house because I dont necessarily "use" the features. And I am quite sure that there are quite some people or FC that barely use their house or might not be interested in decorating it much. Maybe some just own it because they want to hold a event in this once per months.
There are so many different reasons for having a house and there are no rules how you have to use it. So some might be angry because someone bought a house and only visit it once per month to party in this. But its their right and they should not lose it because someone believes that they are not using it enough.
I do agree that those that dont play anymore should not keep their house forever but this could have simply be solved by saying that you need to sub for a certain amount of days or cant have a big break between your sub. This way SE gets money from those that want to keep their house but might not be able to play right now for reasons and anyone that truly does not plan to play anymore wont keep ghost houses. Win Win for everyone imo. (Other than those that feel like only certain people deserve a house.)
(A PVP player also dont need to access their limited mount to keep it, no matter if that person will ever use it again or not. )
