People aren't showing aversion to "subscription vs non-subscription models", they're showing an aversion to greed, and businesses not treating them as a valued customer, but as a resource to be milked until either the resource dries out or the business goes bust.
In the original definition it used to be that a "subscription model" meant a win-win situation for both the user and the business: the business gets some sort of pledge that the customer will continue purchasing the recurring product or service in question because they are a loyal customer, in exchange for extra benefits (typically a discount, or some sort of extra goodies or support).
Now we have the reverse situation: greedy companies treat subscription as their "main" business plan, hoping to milk as much money as ephemerally possible without necessarily valuing their loyal customers, offerring either no non-subscription alternative, or a highly crippled or ridiculous alternative to coerce you into subscribing just to get the "base" product "at least once".
It's become the software equivalent of hardware companies coming up with "bullshit consumables" that serve no real purpose in a device except forcing users to keep paying after a purchase (this is super common in biomed devices!).
People know a greedy model / bullshit service when they see one. As a result, they put off using it as much as they can, and when they finally succumb with a heavy heart and subscribe because they need the "base" product that should have been available without a subscription, they retaliate in other ways that harm the business (e.g. single star reviews, password sharing networks, etc).
