I think it's just not fair.
Twenty-three-time Grand Slam victor Williams gave birth to her daughter Alexis in September and she returned to action in February having missed over a year out since winning the 2017 Australian Open. "Why should I not be seeded if I have the right to be?"
Languishing in 183rd in the rankings after giving birth to her first child previous year, Williams was not guaranteed to be seeded at the grass-court major given she is outside the top 32.
It means the 36-year-old American, victor in 2016 but absent last year because of her pregnancy, will avoid the big names until at least the third round.
Unless a seed withdraws before the start of the tournament, Cibulkova could potentially face Halep or even Williams in the first round.

She has been critical of the WTA ranking system and the disadvantages it places on women who take maternity leave.
It reserves the right to change the women's seedings to "produce a balanced draw" and Williams, whose protected ranking does not guarantee a seeding, clearly is a special case. "I have tried and I should be seeded".
The draw for Wimbledon is Friday; play begins Monday.
"I don't think it's the right thing to do", Cibulkova told British broadcaster BBC ahead of Wednesday's seeding announcement.
The men's seeds show a few tweaks from the ATP rankings with Wimbledon using a formula created to take into account results on grasscourts.
The 36-year-old is ranked world No 183 as she continues her comeback from giving birth to her first child last year but Wimbledon officials have discretion to seed a player regardless of ranking and are understood to have come to a decision at a meeting on Tuesday.
No unseeded woman has won the Wimbledon singles championship. Competitor Caroline Wozniacki and U.S. Tennis Association President Caroline Katrina Adams were also among those who voiced support for Williams. She pulled out of that tournament in the fourth round because of an injury. "Having won so many Grand Slams and being number one for so many years, she deserves a seeding".
