I agree with the OP. The description is very misleading. When a plugin is found within the WordPress directory, users expect to receive the entire list of features that are given on in the plugin's description. If something is a premium feature, it should be listed separately and marked as such. Users shouldn't have to track down your website to read the fine print.
Also, it would be nice if you stated within your description that registration on the Skysa website is required. Yes, I see it in the installation file, but most users don't read that file until after the plugin is installed and a problem comes up.
Those are just personal gripes, but these are quotes from the guidelines that you must follow when your plugin is in the WordPress directory. I don't know if they were somehow missed by those who review the plugins or if these things were changed after submission, but I seriously can't believe the plugin is allowed in the FREE directory.
Trialware is not allowed in the repository. It's perfectly fine to attempt to upsell the user on other products and features, but a) not in an annoying manner and b) not by disabling functionality after some time period.
Your plugin does exactly this. Not only do you list Chat & IM in the features, but you snatch these features away after a few weeks.
The plugin must not embed external links on the public site (like a "powered by" link) without explicitly asking the user's permission. Any such options in the plugin must default to NOT show the link.
From the Skysa FAQ
Can I remove the Skysa logo and other branding?
Yes. With Skysa , you can remove all Skysa branding and logos from your bar by purchasing our Pro plan.
The plugin page in the directory should include no more than 12 tags.
I stopped counting after 30.
