Alternatives to MuseScore.com regarding easy rehearsal, incl looping, for choir members?

Ok, so I got the difference between MuseScore Studio and MuseScore.com, let me nickname the latter "The Platform" in this post. And I get that this forum is about Studio, not about The Platform. But I have an urgent need to rant right now, and in the end I'm going to ask for an alternative to The Platform, which seems better placed among Studio users than Platform users.

I find The Platform immensly aggressive in terms of getting you to subscribe, forcing you to answer questions about your instrument, goal, rehearsal methods, age and more. A lot of bullshit texting, like "There are 1.3M like you, including those that trust MuseScore", what, does it mean you have 1.3M accounts or not? It was hard to find information on what benefit I'd have from a subscription, I was seriously startled to see that my own score seemingly could be downloaded for money, and and and.... responsibly ending mentally not finished rant here.

I found a feature I've really been looking for on The Platform: letting members of my choir view and playback my score, even looping over customly selected bars, and via the mixer button possibly being able to single out their own voice. I understand the idea that a platform has to make money out of something, so that the mixer function is not free, I can totally understand; it can be sorted out by uploading one score for each voice. I'd even advocate for the choir to pay a sort of choir subscription if it in turn let's the individual users use the mixerfunction. But the aggressiveness of the platform, especially when trying to use their android app, really put me off, so I don't want to make it necessary for my fellow choir members to even visit that site.

So: is there an alternative? I saw another app on Google Play, called Musicnotes, but it didn't say, what kind of sheets I can load, and I guessed, they have their own standard.

I have no need for the whole "connecting millions of users and discover trillions of new compositions thingy". I need an easy way for non-note reading choir members to rehearse their voice, especially bars around section transitions. MuseScore Studio is actually really really good and has this feature already inbuilt, but expecting each choir member to download and learn basic navigation in a far too complex for the task desktop app is just not an alternative.

Can the MuseScore Studio player be isolated and run on a VPS? (which is probably what The Platform did to begin with; and if they used MuseScore, that code should also be open source, right?)
