There is a plausible economic incentive to do this:
Reputation.
This happens less in markets with few, big sellers and lots of customers locked into long-term contracts (like ISPs), but it does happen occasionally in high competition markets where customers can take their business elsewhere easily.
Restaurants are a good example - where I live, a host might hand out a round of after-meal shots on the house to encourage a big table of uncomplicated guests to come again.
Hypothesis: what matters here is a social toolbox for engaging with “attractive”/compatible women in a non-romantic/sexual way.
I.e. someone who, even as a teenager, had lots of female friends, is likely to have a learned how to deal with them as persons, beyond “I’d like to hit that”.
(Paradoxically, such a person is more likely to find a romantic partner, because they might have lots of M-F acquaintances/friendships that can potentially become something more.)
Someone who never learned that, can only interact with (to them) attractive women through the lens of “I’d like to hit that”, which has a much higher risk of ending in failure.
If someone in the second category was always raised on the values of romantic success being a requirement for a non-failed life, and possibly with a touch of chauvinism/misogyny, they might wind up caught up in a frustrating loop of failure.
This is how incels can happen.
Because one common assumption was that the universe might contain as much antimatter as matter.
Which begs the question: Where did it go? We would notice a huge amount of annihilation reactions in the solar system.
“Antimatter falls up” (is gravitationally repelled instead of attracted by normal matter) was an easy hypothesis to explain that.
The Behemoth from the Expanse Series had a laser with a range of literal light years.
Granted, it was a comm laser, but they did weaponize it at one point.
Even if we assume that the beam had a solar-system sized diameter after 4 ly, a weaponized output should still be in ship-killer range after an AE or five.
Ultimately, the weapon was never fired (and would have melted half the ship if it ever were).
A TTRPG campaign I wrote and ran two decades ago for a group of friends.
I knew only a fraction of what I know now, was overambitious and railroady - it should have turned into a disaster.
Instead, things just… clicked and we had a few months of gorgeous fun. Years later, one of those friends confessed to still getting goosebumps when a key scene’s theme song plays.
(Obviously, a core reason for this working so well was that we were just a great group.)
When I started playing Shadowrun, I was confused about this as well. Why can I remote access someone’s cyberarm to begin with? The damn thing should have exactly one data connection: To the user’s nervous system. That’s it.
Now that I work in IT, I can tell you that it’s actually extremely realistic.
Most of these systems (yes, even “hardened milspec stuff”) are highly complex tech that only megacorps can design. They aren’t designed for security. They’re designed to sell fast and with the minimum necessary design/production investment.
That wireless access you’re highjacking? It’s probably a maintenance access / private data siphon with a known unpatched CVE. Or an underpaid, overworked designer/dev forgot to remove the wifi module from the prototype spec and fixing that is “somewhere down the roadmap”.
If you try to flash your 'ware with secure FOSS software, you have to overcome safeguards that are designed to prevent it and risk bricking your own arm / inviting an armed “patent protection” corpo squad to your door.
Truly secure custom-build 'ware does exist, made by a small community of independent tech nuts, but making it without a full factory/devteam requires a hideous amount of work and they’re just plain-out inferior than the highly-funded, mass produced corpo crap that doesn’t bother with ITsec.
Most professional runners just have a good decker of their own who will run interference for them (increase RAM cost) or try to trace the hack and disable the source before it completes.
