Why did Prusa placed an openprinttag on all filaments and charges for it?  

RE:

The Prusa app is spyware to me, so I'm not touching it. Not even with an eleven foot pole. If the Prusa app becomes semi-mandatory, then I'll happily sell all my Prusa printers and say bye bye to Prusa. How is it useful if you just outright refuse to use the Prusa app?

There will be NFC readers directly on the printers, integrated in the spool holders. They already gave a sneak peek in some short video.

So I don't think you will need to use the app at all. There certainly should be local functionality within the printer (detecting the filament type). And hopefully there will be some synchronization of information between the printer and PrusaSlicer as well, via PrusaConnect. That's assuming they still have a developer who knows his way around PrusaConnect -- I don't think much has happened at all on that front for at least a year.

I appreciate you mentioning those options. What goes for the app goes for the cloud as well. It's not my cloud, so I'm not feeding it my data. Maybe there is some benefit with PrusaSlicer, but the way that PrusaSlicer is heading on the privacy front, with a lot of tracking and caching and logging about your prints built in without a good way to manage it, PrusaSlicer is becoming less and less appealing with every release.

Basically I don't see any benefits and I couldn't care less about NFC. I see it as a privacy and security risk and a cost burden.

The Prusa ecosystem was great with the MK3S, but it has gone downhill since.

Now that I'm thinking about it, I hadn't really considered the total scope of the data sharing that the printers might be up to. I have the printers on a separate subnet and VLAN, but I think I'll have to review the actual network traffic for these printers, because I'm basically at the point where Prusa is on the black list in terms of privacy.

And please don't get me wrong. I'm not berating or attacking you here. It's just that you are mentioning all the areas of what Prusa has been doing wrong in the areas I care about... 😡

No concerns from me.  I will be happier when they integrate it into printers.
