Honestly $42 seems quite inexpensive depending on how you are using it. Initially I would not have spent any amount on it. However I have recently started using it for very specific tasks and it has been a game changer for my productivity.
I probably have a different use case than most so in my case $42/month would actually be well worth. Relative to how much time it has saved me on a few specific tasks compared to my billable hour rate it has easily saved me 10x what it costs per month and is just in a single week. Even if I only have that need once per month it would still be well worth it.
I hope however that they will keep the free version even if limited and/or maybe even implement a tiered system with maybe a basic version for under $20. But I would still subscribe to a pro version and I would gladly pay $42/month to know that I will always have access and my requests are prioritized.
