You might not be aware that you're ultimately deriving your living from the scraps thrown at you from the corporate world.
Characters are beaten over the head with this endlessly, some players just choose to ignore it because they find it easier to play My Team versus Their Team, and it's convenient for them to justify their personal quarrels as theme enforcement.
Nothing stopping someone from personally taking issue with a specific service mixer in a specific context, but anyone doing it as a rule, or advocating that it should be some kind of enforced norm, is entirely out of lock-step with the described game world.
The divide that came in three years ago was about divorcing service and corporate, and even that went way too far in many cases. Slither specifically underscored in that thread that service mixers should not be broad-brush painted as the Mixer 'enemy' because everyone is struggling against the same system:
if you work as a medic up at a clinic and come back to the mix and patch up gangers or others in your free time-- while telling your mixer friends how you 'accidently' let a Judge die the other day... who's going to give you shit?
If you are a dancer at Korova and you come back to the Mix and tell your mixer friends how you're working on conning some fat cat corpie who loves to pay you for private dances into being your sugar daddy by getting them to fall in love with you so you can rob them blind-- who's going to give you shit!?
Your character doesn't have to actually be doing any of that. Your character doesn't have to believe what they are saying. They just have to get others to believe it. You don't have to be honest with people. You can lie to them. They will probably believe you. Convince them you hate corpies jut as much as they do-- right up until the moment that you get that sweet corporate gig you've been plotting after and you leave the scum behind in the mix forever.
What ended up happening was that nuance was hard, so players made it black and white and decided X service jobs were okay (because they were the jobs people actually wanted and they had faction support) and Y service jobs were bad (because they were isolated and little wanted jobs and easier to punch down on).
The whole blanket persecution thing needs to die yesterday. Conflict should arise of what specific things characters do, not because they had the wrong label.
