Just like how we now look back on the days before the Isekai glut as the golden days, I fear the current reality of free scanlation sites are transient as well. No matter how much we want to deny or disguise it, we are enjoying the fruits of others' commercial labor without directly compensating the creators and licensors.
For now, we're able to mostly go under the radar because of the difficulties in automated detection of almost-but-not-identical manga/wha/hua pages thanks to the armies of scanlators collective efforts, but with the abundance of idle compute cycles, language models, translation technology, and textual inferencing, I can see a time when some company will be able process an image of a manga page, or even partial manga page, and not only source the original work, but also parse the translation to compare it so as to differentiate between Fair Use, derivative work, protected satire/parody, etc. and infringement.
I'm sad all the chapters are now gone. This was one of my 10/10 titles, and even one on my private MDlist of re-readworthy works. However, I have to acknowledge this is the ever-changing landscape in which we wander.
Everything is ephemeral. Nothing exists except as allowed by monied interests, or by their ignorance. And, with datacenters metastasizing, they will be ignorant of fewer and fewer items over time.
