Question; let's say the PCs come to two doors. The DM's planned encounter is behind the left door.
The PCs take the right door... so the DM moves the encounter to behind the right door.
Is this railroading? I'd argue no, even though it is forcing a certain outcome to happen, and keeping with what the GM has planned. But the players still have choice, even if they don't know they're choices may be meaningless.
No, that is absolutely railroading. It is the text book definition IMO
