Yes, that is one theory, although it is strange. It is possible when you have lonely aircraft suddenly appearing in some air defense region, but there is a route where many planes fly every day. Air defense crew always see this on radar, yet at that night they mistake civilian plane for enemy target? Although this is a possible situation. It isn't comparable with MH17 for many reasons.

If that happened, Iran is in bad condition. They already lost many people just at funeral of Suleimani, now they shoot civilian plane. Maybe USA just need to wait.

Another theory, widely circulated in media, is engine failure. Boeing of same type had fan blade failure resulting in one dead passenger (blade penetrated hull) some time ago. This is pretty bad thing, because engine must be protected from this, as regulations stay (engine hull must contain any broken fan blade). Technically it isn't Boeing fail (engine is made by French), but it is Boeing task to control this.

And story about 737 MAX is still going, so Boeing surely doesn't want another reputation hit, and will try to blame everything to move investigation into other side.
