Well for the sake of argument, or perhaps just the pleasure of starting one,
I have become against the practice of mass uploading a bunch of repeater data.. and if someone is relatively new to the hobby, would further say this is a terrible idea.
Every radio I have bought used has come with stuff that I find to be confusing, in the wrong order, incorrect, or just not necessary. For example the tone on Ken's file for Colorado Connection is now 88.5hz, not 123..
If you know your radio, it takes about 1 red light to add a repeater and save it. You should know how to do this. Also know what those repeaters are and what those nicknames are, and decide in what order they are in. If you want to save memory banks and all that I guess that's a fine use of your time for me I don't care to learn it, I'd rather force myself to program new channels in the old fashioned way, and only keep on hand what is needed or useful. I can easily load a few up to prepare for a trip... then remove them. I could also look in a repeater book and get what I need, should I find myself somehow air dropped into different state with no cell coverage and I was stuck or hurt or something.
I helped program a bunch of people's Yaesu's way back when, and also a bunch of Bao UV-3's and UV-5's... and I think I did all those people a disservice. Most came back to me at some point because they forgot which repeater to use, or couldn't access the Breck repeater after it changed, etc. Also when scanning they'd run through all the repeaters in the western hemisphere followed by every simplex channel we know including every Cruise Moab frequency... then miss something. All they really needed was 146.460 and 145.310 to be in the moment that day. I have also witnessed one of them being asked to assist with someone else with the same radio, like "hey you also have a FT78000, I can't seem to hit the Connection, can you help?" only to respond "man I don't know how all that works, Dave programmed mine and I don't want to mess it up." yes, true story. sad.
I also think a lot of people have become less engaged with the hobby because of how easily the answers were handed to them... It's like buying a turnkey rock buggy, the first day you can't point and shoot up a wall you park it back on the trailer, and first instinct is call the guy back you bought it from because you think the front locker isn't working. yet you don't even know which wire is for the air compressor. So rather than dive into it, you just park the rig or only run easy trails.. you probably forgot to turn the hubs.
Not saying we should all buy boards and diodes & start building our own radios, but if you're going to rely on a tool like this, no different from a hi lift jack, first aid kid, winch, you should own up to a basic understanding of how to operate it, and be able to dial in and save a new repeater.
