No one is really insulated. The way I explained it to someone is Reddit was like a girlfriend you dated for 10 years. It was great and it was mostly on autopilot. You both enjoyed each others company. Every so often you would get in a fight but it was never anything too extreme. The API change was like a massive blow up where you two finally say things that cannot be taken back. Afterwards your relationship isn’t really the same. It is not necessarily damaged beyond repair, but one of the two in the relationship is just sorta sitting there thinking “This aint worth it anymore” so they go on a break to take some time. Many people will go back. Many will call it quits. Some will go between Lemmy and Reddit. But things are just not going to be the same moving forward.
