Depends on the context. In the context of the Novice Linear Progression, you start with a weight at which you can exhibit proper technique but which just starts to challenge your completely unadapted system at the 5th rep. Almost every healthy person can add weight linearly for a while from that point. And we're always very clear that that process must take place within the context of excellent form.
In general, can one's pursuit of more weight cause form issues that can be problematic? Yes. Is that a valid critique of the SSLP? I don't see how it is. It's a misunderstanding of it.
