As much as I'd like to believe this, the source is MLID who has been milking this controversy like crazy and is always huffing hopium (because he has one anecdote about AMD backtracking on FSR exclusivity to newer cards and thinks that therefore every company will react like that).
It's not outside of the realm of possibilities that Sony really became so boneheaded that they made such a decision and only afterwards thought about asking what developers for their platform think, and are ready to change plans accordingly, but it sounds very unlikely.
Their whole next-gen strategy relies partially upon a handheld that's naturally not going to play discs. As we can see with this gen, when presented with the option to get a driveless console vs one with a disc drive, the vast majority paid the premium to get the latter. So even if they make a compromise and say games will still release as PS5 discs but PS6 will be full digital (like MLID says they should do), it's just going to make the PS6 an even harder sell by comparison.
Also that 23% physical figure for Wolverine is unofficial and from Alinea Analytics, who always massively underestimate physical ratios. That ratio might be somewhat in the ballpark of what sales in the US look like but in the rest of the world it's going to be much higher than 23%.
