Hello Julien,
The fact that you feel respect has been shown by simply offering free addons is in itself an insult your users. Do you think your users care more about getting something for free to ensuring a smooth migration for their own users to v3? We would much rather pay for the addons and have the migration script in place. For us, the user experience is far more valuable than making quick money.
What about security issues? Can you guarantee that v2 is as secure as v3? No you cannot, as the development ceased a long time ago.
I think you should be ashamed that you’ve continued to develop your premium offering and have not invested sufficient time in supporting your historical users with a migration. Given that it is these same historical users that supported your plugin in the early days.
I encourage you to develop your premium offering, I’m sure your users will find these very useful. But currently, from what you’ve said, clearly you’re doing this at the expense of your historical users.
Again, this is a heavy reason for why the 1* review was provided. Given your behavior thus far how can we be sure that in future your new users will not be subjected to the same treated when a more prosperous opportunity presents itself?
Anyway, there’s no more reason to continue this discussion. Thanks for your time. I’m sure there will be many more historical users that will voice their concerns over the coming months through the use of the review portal.
