1 The factories are planned to be removed.
Is this sentence correct in the context of describing future plans?
I have recently read some sentences that use the structure "be planned to". There are some confusing controversial and contradictory questions and answers regarding this structure.
In that question someone has commented and said that the above sentence is ungrammatical. They have provided an explanation for it but I couldn't comprehend it. The explanation was: ""Factories are planned to be removed" sounds like the reason they are planned is for them to be removed."
I have found other questions regarding this structure. For example, there are also contradictory answer and comment here. There is another question here that suggests there is nothing wrong with the following sentence:
2 The meeting is planned to be held in the coming days.
I have also searched by ludwig and found many examples of this structure. One of them is:
3 The building is planned to be ready for occupancy in the summer of 2001. (The New York Times)
So why there are suggestions and comments about this structure being ungrammatical?
I am confused and I would appreciate it if you could clear things up.
