for me, twitter has been my favourite platform. the things i have gotten out of twitter far outweigh what a monthly service is going to cost me so i can't wait to sign up, i think it's brilliant. you are speaking as someone who works in the social media sector, you are a specialist and you engage with it a lot. if people are browsing while they are waiting in a coffee shop, are they really going to want another subscription on top of all the others they have? i think that's the difference. because i use it every day, and for work, it makes sense for me to buy it. if you just use it casually, you don't spend a lot of time on the platform, not using it for news, sport and politics, i can see it wouldn't fit in for you and you think social media needs to be free,
