Agreed. On the other hand its very possible to rephrase these much better than the site lists, and doing so earns you respect. In a meeting full of people where 1 person overcomplicates an issue, everyone on the call will know 1 person is overcomplicating it.
If you say "Being mindful of timelines. Let’s concentrate on the initial scope." you move the meeting forward but come off as a jerk.
If you say "Those are good thoughts - lets make note of them and circle back at the end of the call" you've moved the meeting forward, the 1 person feels heard and doesn't hate you, and everyone else silently thanks you for skipping the overcomplicated person.
