> Assuming an up round, dilution causes you to own less of a company on a percentage basis, but the actual dollar values of your shares will be worth more.

If you're at a $10M company and you're thinking "I will own 0.1%, so in a few years I can look forward to a payday of $10,000" then you're right: getting diluted 10x to own 0.01% of a $100M company is the same value.

But if your thinking is "I will own 0.1%, and if I owned that much of WhatsApp when it sold to Facebook I'd have made $16M" then a 10x dilution would reduce that to $1.6M

Now, you might argue the second line of thinking is wrong and a fantasy valuation, but we all know no-one's getting hired away from FAANG by the promise of an uncertain, one-off $10k in a few years.
