WordPress.org means installing WordPress software on your own hosting account, giving you full control over themes and plugins. WordPress.com, Squarespace, Wix, and Weebly restrict what you can use, trading customization for convenience.
which means that I use the same software and I install it on my own hosting account, as opposed to WordPress.com. You're using the same software, but they allow you what themes you can use, what plugins you can use, and they limit things like that. And so in that sense, they're the same as Squarespace or Wix or Weebly or any of these other platforms out there.
