I can see two sides to it.
There's a big launch coming soon, which usually involves loads of enquiries from potential customers, and a run through of all the products. No doubt Ali was getting messages about it. She has 4 kids and lots going on and probably just wanted to send out a quick message to all to direct them to the website instead of asking her, so maybe that's why it sounds so cold.
It's odd that she didn't tag The Little One though, just posted it, so Janette had to screenshot it to repost it. Neither of them directly thanked the other for their help / said about how great of a time they had together, etc. so it does seem a bit off.
For anyone not around at the time, originally Ali stepped in to help Janette at the last second as she had a miscarriage just before a launch went live, and the website shat itself mid launch and she couldn't handle the messages from people giving out about it with all she had going on already (understandable!). Ali really saved the day, she just came in and took over the launch. Then there was a collab that followed and they just kept working together until they quite suddenly didn't anymore.
It does always surprise me how many holidays she goes on for a self employed person (and she goes on more than she posts, she was on my flight back from Spain a couple years ago and that holiday never made the 'gram). Ali appears to live a much more simple life, yet also appeared to be putting in a lot of work for TLO.
