Looking at this today, here are a few reasons for why it may not be adopted on a wider scale.

Looking for their web clipper extensions

• I see no extension in the Firefox store. The source code is at GitHub. Most won't bother.
• I see an extension for chrome. Yay! However, in the permissions section, for those privacy minded, it appears to request permission to "read and change all your data on all websites." Had this been a Firefox extension this would mean it can see all of your passwords and anything you see on the Web. This is probably also true for chrome but I can't state it as fact. Perhaps someone can explain why this isn't a red flag.

If you want to sync between different devices, it's great that it supports a sync server. However, how many users are going to self host a server? 1% or less of the population? For the remaining 99%... The website appears to be silent as to how to manually sync between two or more desktop computers manually. Maybe it can be done? I don't eat to be the first to try

Look at the details of the upgrade path. It looks rough going. And issues at GitHub reflect this . Take a look.

A single SQL lite database file hiddenly stores everything. This is scary for those of us who have lost our data on other SQL lite platforms like the darktable photo editor. SQL lite databases are supposed to be so reliable they say... Until they are not.

Markdown does not appear to be it's standard. That can be good or bad 😔
For me that might be bad because the more privacy friendly markdown web clippers might not work . I'll have to try .

That's a lot of friction to overcome. Not to mention the extent of cross platform support compared to logseq. Still, I might quickly try it just because of it's code notes and math notes. I could really use these. In fact I may only use it for those and use logseq for web and general knowledge stuff.

I hope someone can correct any misinterpretations I've made. Please feel free. I'm trying to like Trillium.
