You don't have to agree, but it doesn't have the same effect.

The reality is the company is releasing software to customers that have no way of using the source code to that software under an open source license. You can claim this is somehow open source because they will eventually be able to use the source code under an open source license, but that doesn't make the software open source today, any more than you can lock someone in jail and claim they're actually free because they'll get out in two years.
