I work in digitization at a major institution, specifically on film scanning (among other things). The position of literally everyone who works in this area (including curators especially) is that we should make everything freely available online. Like you say, data doesn't exist unless it's accessible. We feel great pride in making things freely available to the world.
The reason why in every case where we can't make something public is the copyright holder. Polish copyright law on photographs is similar to the US and elsewhere - retroactively applied to 70 years after the photographer's death (the copyright law previously would have put these in the public domain already, but the new law retroactively put these back in copyright).
The institution may own the negatives, but not the copyright - this is standard. So any use requires permission from the copyright holder. Many copyright holders (which often is the estate of the photographer who is no longer alive) are happy to have the images be digitized and available for the public to see, but others emphatically are not for a variety of reasons.
I have no particular knowledge of the situation here. It could very well be that it's the museum itself being stingy and wanting people to come see them in person. But it's not like institutions digitize things for you to see online because they don't want you to come in person. The number of people who are going to go to this museum specifically to see these images is extremely small - mainly niche researchers and historians. So I'm just speculating that it's likely or at least very possible the copyright holder (the son of the photographer it sounds like) is enforcing restrictions on it, because that is extremely common.
