Exactly, it's not about being literally unconstrained, but a lot of biology PhD programs turn into "follow my advisor's weekly (sometimes even daily) instructions to the letter". This can be very demoralizing and it is concerning for the development of future PIs as well.
In addition to micro-management of the thesis project, there's also consideration of outside academic activities. Many students end up spending 50+ hours per week on the work their advisor designed. This leaves little time for the student to explore learning new skills that might be relevant to them - for example programming tutorials, a reading group in a different subfield, mentoring an undergrad project, communicating with the general public, etc.
Obviously there is not time for every PhD to involve all of those things, but currently it is much too restricted. For some people to the point that their advisor forbids them from taking a night class or whatever despite the fact it is outside the (already overtime) working hours of the lab. Research may indeed be the priority, but entirely ignoring other parts of the academic role has not gotten us anywhere good.
What it boils down to is that part of the compensation of the PhD is supposed to be training. Yet as it stands many students are treated as only employees, with no regard to teaching them to become a better researcher and no time allowed for their own personal/career development activities.
Students are being lied to for sure (at least in certain fields/locations). But the solution is not to just be blatantly honest about what PhD currently entails. Part of the shift also needs to be a return to considering the PhD as an important piece of the training for becoming an academic.
