There is nothing deceptive about saying Core did not deliver on their promise to increase the block size. We still don't have a block size increase. Saying that SegWit provides the promised increase is deceptive. SegWit provides a theoretical 1.7x increase but only if everyone switches to SegWit transactions. To send a SegWit transaction you must upgrade your software, understand how to configure it to send SegWit transactions and be sure that the receiver's software understands SegWit. The only conclusion is that SegWit's effective block size increase will not take effective immediately.
Regardless, Core signed an agreement with a majority of miners that they would implement a block size increase, not an effective block size increase but a real one. They reneged on this promise and are instead telling everyone that they are going to do as they please because miners don't control BitCoin.
