Let me translate this development for those a little
In the 80s and 90s Disney used to, sporadically, release home VHS tapes of "Disney Classics" for a limited time. These were big deals as they were released unannounced and subsequently withdrawn to stoke demand. Resale value on rare VHS tapes USED to be profitable for video retailers and studios. Now, in 2019, Disney has made its tradtional animation movies open resource, for a streamng fee.
So Disney has tried applying the above model in 2019, a time of internet file sharing, secondhand blu-rays aplenty and ALIEN being found in a charity shop for £0.50p if you look- to the live action film ALIEN. Only this time its moreso Disney is saying a classic installment of ALIEN being widely available might invoke a "deductive" opinion of future projects.
I doubt any more cheap sequels or TV streaming projects of the "alien brand" will affect people's knowledge of how to spot a stinker. You don't need comparison's to know if a classic has touched you or you are watching formulaic crap.
All this will do is harm arthouse cinema screenings of ALIEN.
