About GitHub Copilot in specific: One big negative was how when GPT-4 became available that Microsoft didn't upgrade paying Copilot users to it, they simply branded this "coming soon"/"beta" Copilot X for a while. We simply cancelled the only Copilot subscription we had at work.
Copilot subscription?
I've been getting monthly emails that my free access for GitHub Copilot has been renewed for another month… for years. I've never used it, I thought that all GitHub users got it for free.
There's a free tier, and various paid tiers: https://github.com/features/copilot/plans
If you are a student or maintain a popular open source project, they give it to you for free. I’m guessing you might fall under that category.
Besides the sibling replies to your comment, GitHub’s Copilot free plan (not the specifically free for just OSS and students) was also launched relatively later: https://github.blog/news-insights/product-news/github-copilo...
